Neurofibromatoza typu 1
Objawy

Neurofibromatoza typu 1 (NF1) to genetyczna choroba o zmiennym przebiegu klinicznym, manifestująca się głównie w dzieciństwie. Charakterystyczne objawy to liczne plamy café-au-lait (>6), piegi w dołach pachowych i pachwinach, nerwiakowłókniaki skórne i podskórne oraz nerwiakowłókniaki splotowate (występujące u 25-50% pacjentów), które mogą powodować ból, deficyty neurologiczne i transformację nowotworową (MPNST w 10-15% przypadków). Występują także zmiany oczne, takie jak guzki Lischa i glejaki nerwu wzrokowego, oraz problemy neurologiczne (trudności w uczeniu się, ADHD, napady padaczkowe) i kostne (skolioza, deformacje kości długich, obniżona gęstość mineralna kości). Tempo wzrostu guzów jest największe we wczesnym dzieciństwie (20-240% rocznie), a w dorosłości spada poniżej 5% rocznie.

Objawy Neurofibromatozy typu 1

Neurofibromatoza typu 1 (NF1) to choroba genetyczna, która zazwyczaj jest diagnozowana w dzieciństwie. Objawy są widoczne już przy urodzeniu lub pojawiają się wkrótce po nim, a prawie zawsze występują do 10. roku życia. Nasilenie objawów może być różne – od łagodnych do umiarkowanych, a ich manifestacja może znacznie różnić się u poszczególnych pacjentów, nawet w obrębie tej samej rodziny.123

Objawy skórne

Do najbardziej charakterystycznych objawów NF1 należą zmiany skórne:

  • Plamy typu café-au-lait (koloru kawy z mlekiem) – płaskie, jasnobrązowe plamy na skórze. Osoby z NF1 mają zwykle więcej niż sześć takich plam. Plamy te często są obecne przy urodzeniu lub pojawiają się w pierwszych latach życia. Po okresie dzieciństwa nowe plamy przestają się pojawiać.123
  • Piegi w dołach pachowych lub w pachwinach. Piegi te zazwyczaj pojawiają się między 3. a 5. rokiem życia. Są mniejsze niż plamy café-au-lait i występują w skupiskach w fałdach skórnych.12
  • Nerwiakowłókniaki – miękkie, wielkości grochu guzki na skórze lub pod skórą. Te łagodne guzy zwykle rosną w skórze lub pod nią, ale mogą również rozwijać się wewnątrz ciała. Nerwiakowłókniaki mogą zwiększać swoją liczbę wraz z wiekiem, zwykle pojawiając się w okresie dojrzewania lub wczesnej dorosłości.123
  • Nerwiakowłókniaki splotowate (plexiform neurofibromas) – większe guzy, które obejmują wiele nerwów i otaczających tkanek. Występują u około 50% pacjentów z NF1 i mogą powodować ból, deficyty neurologiczne i nieprawidłowości w obrębie zajętych lub sąsiednich struktur.123

Objawy oczne

NF1 może wpływać na narząd wzroku, powodując:

  • Guzki Lischa – małe guzki na tęczówce oka. Są one trudne do zauważenia i nie wpływają na wzrok.12
  • Glejaki nerwów wzrokowych (optic pathway glioma) – guzy na nerwie łączącym oko z mózgiem. Glejaki te zwykle pojawiają się do 3. roku życia i mogą wpływać na wzrok, chociaż większość z nich jest bezobjawowa.123

Objawy neurologiczne i poznawcze

Problemy neurologiczne i poznawcze występujące w NF1 obejmują:

  • Trudności w uczeniu się – u dzieci z NF1 często występują problemy z nauką. Często jest to konkretna trudność w uczeniu się, np. problemy z czytaniem lub matematyką.12
  • ADHD (zespół nadpobudliwości psychoruchowej z deficytem uwagi) i opóźnienie mowy są również powszechne.12
  • Powiększona głowa – dzieci z NF1 często mają większą niż przeciętna głowę z powodu zwiększonej objętości mózgu.12
  • Bóle głowy – są częstsze u osób z NF1 niż w populacji ogólnej.12
  • Napady padaczkowe – występują rzadziej, ale mogą być objawem NF1.12

Objawy kostne

Zmiany w układzie kostnym w przebiegu NF1 obejmują:

  • Skoliozę – boczne skrzywienie kręgosłupa, które może wymagać leczenia za pomocą gorsetu lub operacji.123
  • Deformacje kości długich – szczególnie podudzia i przedramienia.12
  • Niski wzrost – dzieci z NF1 często są niższe niż przeciętnie.12
  • Obniżoną gęstość mineralną kości, która zwiększa ryzyko osteoporozy.12

Progresja choroby

Neurofibromatoza typu 1 jest chorobą przewlekłą, która zwykle postępuje z czasem, choć tempo progresji może być różne u różnych pacjentów.12

Progresja w różnych okresach życia

NF1 ma charakterystyczny przebieg w zależności od wieku pacjenta:

  • Okres noworodkowy i wczesne dzieciństwo: Większość noworodków z NF1 nie ma objawów, ale niektóre mogą mieć zakrzywione kości podudzia. Do pierwszego roku życia większość dzieci z NF1 ma już kilka plam café-au-lait.12
  • Wczesne dzieciństwo (3-5 lat): Pojawiają się piegi w dołach pachowych i pachwinach.12
  • Późne dzieciństwo: Mogą pojawić się guzki Lischa na tęczówce oka i glejaki nerwu wzrokowego, które zwykle rozwijają się do 6. roku życia.12
  • Okres dojrzewania i wczesna dorosłość: Pojawiają się lub zwiększają się nerwiakowłókniaki, szczególnie skórne i podskórne. U nastolatków mogą też nasilić się problemy z kręgosłupem.12

Czynniki wpływające na progresję

Istnieją czynniki, które mogą wpływać na przebieg choroby i nasilenie objawów:

  • Zmiany hormonalne: Okresy zmian hormonalnych, takie jak dojrzewanie-plciowe/” title=”dojrzewanie płciowe” class=”to-tag” data-termid=”21694″>dojrzewanie płciowe lub ciąża, mogą powodować zwiększenie liczby nerwiakowłókniaków lub przyspieszenie ich wzrostu.123
  • Czynniki genetyczne: Badania wskazują, że określone warianty genetyczne mogą być związane z szybszą progresją choroby.12
  • Wiek: Szybkość wzrostu guzów NF1 jest zazwyczaj największa we wczesnym dzieciństwie, a z wiekiem zwalnia. W dzieciństwie guzy mogą zwiększać swoją objętość o 20% do 240% rocznie, podczas gdy w dorosłości wzrost powyżej 20% jest rzadki, a większość guzów rośnie mniej niż 5% rocznie.12

Nerwiakowłókniaki splotowate i ich progresja

Nerwiakowłókniaki splotowate (plexiform neurofibromas, PN) zasługują na szczególną uwagę ze względu na ich potencjał do powodowania poważnych powikłań:

  • Występują u około 25-50% pacjentów z NF1.123
  • Zwykle są obecne od urodzenia lub rozwijają się we wczesnym dzieciństwie.12
  • Mogą powodować ból, zaburzenia funkcji motorycznych oraz problemy z pęcherzem moczowym i jelitami.12
  • W około 10-15% przypadków mogą przekształcić się w nowotwory złośliwe (złośliwe guzy osłonek nerwów obwodowych – MPNST).12

Powikłania Neurofibromatozy typu 1

Powikłania NF1 mogą różnić się nasileniem, nawet w obrębie tej samej rodziny. Ogólnie rzecz biorąc, powikłania występują, gdy guzy wpływają na tkankę nerwową lub uciskają na narządy wewnętrzne.12

Powikłania neurologiczne

Do najczęstszych powikłań neurologicznych należą:

  • Problemy poznawcze i trudności w uczeniu się – występują u około 50-75% pacjentów z NF1.12
  • Padaczka – występuje rzadziej, ale jest istotnym powikłaniem neurologicznym.12
  • Wodogłowie – nagromadzenie nadmiaru płynu w mózgu.12
  • Ból przewlekły – szacuje się, że około 35-53% pacjentów z NF1 doświadcza bólu przewlekłego, w porównaniu do około 25% populacji ogólnej.12

Powikłania kostne

Zmiany w układzie kostnym mogą prowadzić do następujących powikłań:

  • Skolioza – występuje u około 15-20% pacjentów z NF1, czasami wymaga leczenia za pomocą gorsetu lub operacji.12
  • Deformacje kości długich, które mogą prowadzić do złamań i problemów z gojeniem.12
  • Rzekome stawy (pseudoarthrosis) – poważne powikłanie występujące głównie w kościach piszczelowych.12

Powikłania oczne

Problemy oczne związane z NF1 obejmują:

  • Glejaki nerwu wzrokowego – mogą powodować utratę wzroku, jeśli nie są wcześnie wykryte i leczone.12
  • Zez – może występować u dzieci z NF1.1
  • Wytrzeszcz oka – może być spowodowany guzami w okolicy oczodołu.1

Powikłania naczyniowe i sercowo-naczyniowe

Problemy sercowo-naczyniowe w NF1 obejmują:

  • Nadciśnienie tętnicze – może być spowodowane zwężeniem tętnicy nerkowej lub guzem nadnercza (pheochromocytoma).12
  • Choroby naczyń krwionośnych – włączając zwężenie tętnic i chorobę moyamoya (zwężenie głównych naczyń krwionośnych do mózgu).12
  • Wady serca wrodzone – występują rzadziej, ale mogą być powikłaniem NF1.12

Powikłania onkologiczne

Pacjenci z NF1 mają zwiększone ryzyko rozwoju nowotworów:

  • Złośliwe guzy osłonek nerwów obwodowych (MPNST) – najczęściej powstają z nerwiakowłókniaków podskórnych lub splotowatych.12
  • Zwiększone ryzyko innych nowotworów, w tym raka piersi, białaczki, raka jelita grubego, guzów mózgu i niektórych rodzajów nowotworów tkanek miękkich.123
  • Guzy nadnerczy (pheochromocytoma) – łagodne guzy, które wytwarzają hormony podwyższające ciśnienie krwi.12

Wpływ na jakość życia i aspekty psychospołeczne

NF1 może mieć istotny wpływ na życie codzienne pacjentów:

  • Problemy z wyglądem – widoczne objawy NF1, takie jak plamy café-au-lait, liczne nerwiakowłókniaki w okolicy twarzy lub duże nerwiakowłókniaki, mogą powodować niepokój i stres emocjonalny.12
  • Depresja, lęk i niska samoocena – mogą być spowodowane dużymi guzami lub guzami na twarzy.12
  • Wpływ na funkcjonowanie społeczne – dzieci z NF1 mogą mieć trudności z dostosowaniem się w szkole, co może powodować depresję i martwić rodziców.12

Przebieg Neurofibromatozy typu 1 w różnych okresach życia

Przebieg NF1 różni się w zależności od wieku pacjenta, a objawy mogą pojawiać się i nasilać w charakterystycznych momentach życia.12

Noworodki i niemowlęta

U noworodków i niemowląt z NF1 mogą być widoczne następujące objawy:

  • Plamy café-au-lait obecne przy urodzeniu lub pojawiające się w pierwszym roku życia.12
  • Problemy z kośćmi, takie jak zakrzywione kości podudzia.12
  • Nerwiakowłókniaki splotowate mogą być obecne od urodzenia, choć często nie są rozpoznawane do późniejszego wieku.12

Dzieci w wieku przedszkolnym i wczesnoszkolnym

W wieku 3-10 lat mogą pojawiać się lub nasilać następujące objawy:

  • Piegi w dołach pachowych i pachwinach (zwykle między 3. a 5. rokiem życia).12
  • Trudności w uczeniu się i problemy z uwagą (ADHD).12
  • Glejaki nerwu wzrokowego (najczęściej do 6. roku życia).12
  • Opóźnienia rozwojowe – dzieci z NF1 mogą wolniej chodzić, mówić i osiągać inne kamienie milowe rozwoju niż większość dzieci.12

Okres dojrzewania

W okresie dojrzewania obserwuje się znaczące zmiany w przebiegu choroby:

  • Pojawienie się lub zwiększenie liczby nerwiakowłókniaków skórnych i podskórnych.12
  • Rozwój guzków Lischa na tęczówce oka – obecne u 97-100% pacjentów z NF1 po okresie dojrzewania.1
  • Nasilenie skoliozy – często pojawia się lub pogarsza w okresie skoku wzrostowego w okresie dojrzewania.12
  • Wczesne lub opóźnione dojrzewanie płciowe.12

Dorosłość i ciąża

W dorosłości NF1 może manifestować się następująco:

  • Dalszy rozwój nerwiakowłókniaków, choć tempo wzrostu guzów zwykle zwalnia (mniej niż 5% rocznie).12
  • W czasie ciąży może nastąpić zwiększenie liczby lub rozmiaru nerwiakowłókniaków. Kobiety z NF1 w ciąży mogą również doświadczać problemów takich jak zwężone tętnice i nadciśnienie.123
  • Zwiększone ryzyko nowotworów, szczególnie raka piersi u kobiet – zaleca się rozpoczęcie badań przesiewowych w kierunku raka piersi w wieku 30 lat, wcześniej niż w populacji ogólnej.12

Zmienność kliniczna i prognoza

Neurofibromatoza typu 1 charakteryzuje się dużą zmiennością w przebiegu klinicznym i rokowaniu.12

Zmienność objawów

Objawy NF1 mogą znacznie różnić się nawet wśród członków tej samej rodziny:

  • Około 60% pacjentów z NF1 ma łagodne do umiarkowanych objawy przez całe życie.12
  • Około jedna trzecia pacjentów doświadczy poważniejszych powikłań w pewnym momencie życia.12
  • Objawy mogą się z czasem nasilać lub pozostawać stabilne.12

Czynniki wpływające na rokowanie

Na rokowanie w NF1 wpływają różne czynniki:

  • Lokalizacja i liczba guzów – guzy uciskające na ważne struktury anatomiczne mogą prowadzić do poważniejszych powikłań.12
  • Transformacja nowotworowa – ryzyko przekształcenia nerwiakowłókniaka w nowotwór złośliwy (MPNST) wynosi około 10-15% w ciągu życia.12
  • Obecność powikłań sercowo-naczyniowych – może skrócić oczekiwaną długość życia.12

Oczekiwana długość życia

Wpływ NF1 na oczekiwaną długość życia jest zróżnicowany:

  • Większość pacjentów z NF1 ma normalną lub nieznacznie skróconą oczekiwaną długość życia.12
  • Średnie skrócenie oczekiwanej długości życia wynosi około 8-15 lat w porównaniu do populacji ogólnej.12
  • Główne przyczyny zwiększonej śmiertelności to nadciśnienie, następstwa zmian w rdzeniu kręgowym i nowotwory złośliwe.12

Monitorowanie i regularne badania kontrolne są kluczowe dla wczesnego wykrywania powikłań i poprawy rokowania pacjentów z NF1.12

Znaczenie regularnej obserwacji i wczesnego leczenia

Ze względu na zmienność objawów i potencjalne powikłania, pacjenci z NF1 wymagają regularnej, kompleksowej opieki medycznej.12

Monitorowanie objawów

Regularne monitorowanie jest kluczowe dla wczesnego wykrywania i leczenia powikłań:

  • Coroczne badania kontrolne obejmujące ocenę skóry pod kątem nowych nerwiakowłókniaków lub zmian w istniejących.12
  • Regularne badania okulistyczne do wykrywania glejaków nerwu wzrokowego.12
  • Monitorowanie ciśnienia krwi – zaleca się regularne pomiary ciśnienia krwi, zwykle co najmniej raz w roku.12

Objawy alarmowe wymagające pilnej konsultacji

Pacjenci i ich opiekunowie powinni być świadomi objawów wymagających natychmiastowej konsultacji lekarskiej:

  • Nowy lub nasilający się ból, szczególnie długotrwały lub nawracający, lub ból, który budzi dziecko lub nie pozwala zasnąć.12
  • Drętwienie, mrowienie lub osłabienie kończyn.12
  • Zmiany w nerwiakowłókniakach, takie jak utrzymujący się ból, szybki wzrost lub stwardnienie – mogą wskazywać na transformację nowotworową.12
  • Nowe, utrzymujące się lub zmieniające się bóle głowy.12
  • Problemy ze wzrokiem lub wytrzeszcz gałek ocznych.12

Choć Neurofibromatoza typu 1 jest chorobą przewlekłą i postępującą, odpowiednie monitorowanie i wczesne leczenie mogą znacząco poprawić jakość życia pacjentów i zapobiec rozwojowi poważnych powikłań.123

    Neurofibromatosis type 1 (NF1) usually is diagnosed during childhood. Symptoms are seen at birth or shortly afterward and almost always by age 10. Symptoms tend to be mild to moderate, but they can vary from person to person. […] Symptoms include: […] Flat, light brown spots on the skin, known as cafe au lait spots. These harmless spots are common in many people. But having more than six cafe au lait spots suggests NF1. They often are present at birth or appear during the first years of life. After childhood, new spots stop appearing. […] Freckling in the armpits or groin area. Freckling often appears by ages 3 to 5. Freckles are smaller than cafe au lait spots and tend to occur in clusters in skin folds. […] Tiny bumps on the iris of the eye, known as Lisch nodules. These nodules can’t easily be seen and don’t affect vision.

    Soft, pea-sized bumps on or under the skin called neurofibromas. These benign tumors usually grow in or under the skin but can also grow inside the body. A growth that involves many nerves is called a plexiform neurofibroma. Plexiform neurofibromas, when located on the face, can cause disfigurement. Neurofibromas may increase in number with age. […] Bone changes. Changes in bone development and low bone mineral density can cause bones to form in an irregular way. People with NF1 may have a curved spine, known as scoliosis, or a bowed lower leg. […] Tumor on the nerve that connects the eye to the brain, called an optic pathway glioma. This tumor usually appears by age 3. The tumor rarely appears in late childhood and among teenagers, and almost never in adults. […] Learning disabilities. It’s common for children with NF1 to have some trouble with learning. Often there is a specific learning disability, such as trouble with reading or math. Attention-deficit/hyperactivity disorder (ADHD) and speech delay also are common.

    https://www.ncbi.nlm.nih.gov/books/NBK1109/
    Neurofibromatosis 1 (NF1) is a multisystem disorder characterized by multiple caf au lait macules, intertriginous freckling, multiple cutaneous neurofibromas, and learning disability or behavior problems. […] About half of people with NF1 have plexiform neurofibromas, but most are internal and not suspected clinically. Plexiform neurofibromas can cause pain, neurologic deficits, and abnormalities of involved or adjacent structures. […] Less common but potentially more serious manifestations include optic nerve and other central nervous system gliomas, malignant peripheral nerve sheath tumors, scoliosis, tibial dysplasia, vasculopathy, and gastrointestinal, endocrine, or pulmonary disease. […] The cardinal clinical manifestations of NF1 include multiple caf au lait macules, intertriginous freckling, multiple cutaneous neurofibromas, subcutaneous or deep nodular neurofibromas, plexiform neurofibromas, and characteristic ocular signs.

    Larger than average head size. Children with NF1 tend to have a larger than average head size due to increased brain volume. […] Short stature. Children who have NF1 often are below average in height. […] Complications of neurofibromatosis type 1 (NF1) vary, even within the same family. Generally, complications occur when tumors affect nerve tissue or press on internal organs. […] Complications of NF1 include: […] Neurological symptoms. Trouble with learning and thinking are the most common neurological symptoms associated with NF1. Less common complications include epilepsy and the buildup of excess fluid in the brain. […] Concerns with appearance. Visible signs of NF1 can include widespread cafe au lait spots, many neurofibromas in the facial area or large neurofibromas. In some people this can cause anxiety and emotional distress, even if they’re not medically serious.

    Freckling: People with NF1 often have freckles in unusual places such as the armpit or the groin. They also tend to appear later (between ages three and five). Skin freckles are smaller than caf au lait spots. […] Neurofibromas: These are benign swellings around nerves, which are usually seen as small lumps in or under the skin. Neurofibromas are not normally seen in young children, but tend to increase in number and size around puberty and in adult life. They are usually small and generally cause no physical symptoms. […] Lisch nodules: These are small freckles within the iris (the coloured part of the eye). Lisch nodules develop by puberty in people with NF1. They are usually seen only on examination with a special lamp, and never affect vision or cause other symptoms. […] Other common features of NF1 include: learning difficulties, which may cause some problems at school; headaches, which are more common in children with NF1 than in the general population.

    Skeletal symptoms. Some children have bones that didn’t form as usual. This can cause bowing of the legs and fractures that sometimes don’t heal. NF1 can cause curvature of the spine, known as scoliosis, that may need bracing or surgery. NF1 also is associated with lower bone mineral density, which increases the risk of weak bones, known as osteoporosis. […] Changes in vision. Sometimes a tumor called an optic pathway glioma develops on the optic nerve. When this happens, it can affect vision. […] Increase in symptoms during times of hormonal change. Hormonal changes associated with puberty or pregnancy might cause an increase in neurofibromas. Most people who have NF1 have healthy pregnancies but will likely need monitoring by an obstetrician who is familiar with NF1. […] Cardiovascular symptoms. People who have NF1 have an increased risk of high blood pressure and may develop blood vessel conditions.

    Your symptoms and how severe they are can change over time. Its important to tell your doctor about any new symptoms or changes to existing symptoms. […] Neurofibromatosis type 1 (NF1) is a lifelong condition that usually gets worse over time. It affects everyone who has it differently. […] As the condition gets gradually worse and can cause serious problems, it can affect life expectancy. Your care team will be able to speak to you about this if you want to know more. […] Sometimes neurofibromatosis type 1 (NF1) can lead to further problems or serious complications. […] These can include: high blood pressure, bone and joint problems some children have weak bones that can cause bowed legs or a curved spine (scoliosis), a tumour on the nerve to the eye (optic nerve), which can cause vision problems, depression, anxiety and low self-esteem caused by large tumours or tumours on your face, cancer some tumours can become cancerous and theres a higher risk of developing certain types of cancer, including breast cancer and brain cancer. […] If you have NF1 and are pregnant, you may get problems, such as narrowed arteries and high blood pressure. You may also get more tumours, or your tumours may get bigger and be itchy.
  • #1 Neurofibromatosis Type 1 (for Parents) | Nemours KidsHealth
    https://kidshealth.org/en/parents/nf.html
    Neurofibromatosis type 1 (NF1) is a genetic condition. It causes benign (not cancerous) tumors to grow in and under the skin, often with bone, hormone, and other problems. Most kids with NF1 have mild symptoms that don’t limit what they can do. Most newborns with neurofibromatosis type 1 have no symptoms, but some have curved lower leg bones. By their first birthday, most children with NF1 have several skin spots, called caf-au-lait („coffee with milk”) spots because of their color. Children with NF1 may be slower to walk, talk, and reach other milestones than most kids. They also may have: bumps in and under the skin (called neurofibromas), a head that looks large for the body, headaches, trouble learning, attention problems and hyperactivity, a shorter height than most children the same age, side-to-side curves in the backbone (scoliosis), curving, thinning, or weakness of the forearms or lower leg bones, freckles in their armpits or in the crease between the belly and hip (groin). The symptoms of NF1 are mild in some children, but severe in others.

    Adolescence for both genders may precipitate the development of subcutaneous and cutaneous neurofibromas. Increase in the size of existing neurofibromas and the appearance of new neurofibromas during pregnancy is a frequent observation in women with NF1. […] Scoliosis in NF1 is often mild, but a subset of children younger than 10 years develop a more rapidly progressive form of scoliosis that requires aggressive intervention. […] Although most individuals with neurofibromatosis type 1 (NF1) lead relatively long and healthy lives, the overall life expectancy may be reduced by on average 8 years. The major causes for this increased morbidity and subsequent mortality are hypertension, sequelae of spinal cord lesions, and malignancy.

    Developmental delay (30.0% vs 3.1%, p=0.036), PN (28.6% vs 5.7%, p=0.030), and NF1+ (71.4% vs 30.2%, p=0.011) was more commonly observed in familial cases. […] The common phenotypes exhibiting progression were developmental delay in language (N=7) or fine motor (N=3) according to KICDT. […] In the follow-up WBMRI, the radiologic aspects, optic nerve signal change or thickening, were newly developed in eight patients. Additionally, optic nerve signal change and severe PN (one patient), severe PN and diffuse superficial neurofibroma (one patient), nerve root tumor (one patient), brain tumor on pons (one patient), and neuroblastoma in the left adrenal gland (one patient) were also newly developed. […] Clinical and genotypic features were compared between patients experiencing or not experiencing disease progression.

    https://www.medicalnewstoday.com/articles/nf1-pn-progression
    Rapid NF1-PN growth and symptom progression are typical during early childhood, but disease progression can occur at any time. […] NF1-PN generally develops at birth or in early childhood, growing most rapidly before 5 years of age. During the early years, NF1-PN typically progresses at the fastest rate, with tumors potentially increasing in volume by 20% to 240% per year. […] As people age, NF1-PN tumor growth usually slows. In adulthood, tumor growth greater than 20% is uncommon, and available data suggests that most increase in size by less than 5% annually. […] People with NF1-PN may experience various symptoms depending on how the tumors affect their nerves. These symptoms may change over time as tumors grow or shrink. […] A 2018 review involving 41 people with NF1-PN looked at how the symptoms associated with these tumors change over time. Over approximately 6.5 years, more people reported symptoms related to pain, motor dysfunction, and bladder and bowel problems.

    Freckling in the armpits or the groin. This usually appears by age 5. Freckles are similar in appearance to caf au lait spots but smaller. Freckling can happen in other conditions, but the freckling alongside other common symptoms can indicate NF1. […] Soft, pea-sized bumps called neurofibromas. These are common and can appear on the skin (known as cutaneous), under the skins surface (subcutaneous), or on any nerve throughout the body. Although some cutaneous neurofibromas develop in childhood, most appear during or after the teenage years and may occur more often with age. […] Plexiform neurofibromas. These happen in about 50% of patients with NF1 and involve multiple nerves and surrounding tissues near nerves and organs in the body. About 10-15% of the neurofibromas can become dangerous over a persons lifetime and turn into a malignant tumor of nerve coverings.
  • #1 Pain in Neurofibromatosis Type 1 – Neurofibromatosis Midwest
    https://www.nfmidwest.org/article/pain-in-neurofibromatosis-type-1/
    One of most common challenges for individuals with NF1 is living with chronic pain. By definition, chronic pain is persistent pain that continues for weeks, months, or even years. This occurs when the pain signals within a persons nerves continue to fire, and the severity can vary by individual. In general, it is estimated that about 25% of the general U.S. population ages 20 and over report pain lasting greater than 24 hours. In patients with NF1, estimates of those experiencing chronic pain range from 35 to 53%. […] What are some of the NF1-related symptoms and conditions that cause pain? Probably the most common of these is plexiform neurofibromas, or PNs. PNs are benign tumors comprised of a proliferation of cells in the nerves. They are found in about 30 to 50% of people with NF1. Most often, they grow rapidly during childhood, although they may go for years without being detected.

    The symptoms of neurofibromatosis type 1 (NF1) are often mild. But some people have symptoms that cause problems. […] How severe the symptoms are usually depends on where the tumours are in your body and how big they are. […] Many of the symptoms are there from birth or start during early childhood, but some do not appear until later. […] Symptoms of NF1 can include: light brown patches of skin (caf-au-lait spots) these may be harder to see on brown and black skin, freckles in your armpits or around the tops of your legs, lumps on or just under your skin (neurofibromas) that can be painful or itchy these tend to appear during the teenage years or early 20s, yellow-brown raised dots on the coloured part of your eye (iris) that do not usually affect vision, eye problems, such as a squint, reduced vision, or a bulging eye (which can sometimes cause further symptoms like headaches or feeling and being sick), a large head and below average height, learning difficulties.

    Neurofibromatosis type 1 (NF1) is a condition that causes the abnormal growth of pigment cells in the skin. It also causes noncancerous (benign) tumors along nerves in the skin, brain, and other parts of the body. NF1 is often not life-threatening. But other problems may occur over time. These may include seizures, developmental delay, and increased risk for cancerous and noncancerous tumors. […] Symptoms for NF1 include: […] Skin lesions. These can include light-brown spots or freckles in the underarms and groin. The light-brown spots are called caf-au-lait spots. These skin lesions are not harmful. But they may make a child feel self-conscious. […] Lisch nodules. These are lesions on the colored part of the eye (the iris). They may be found during a routine eye exam. […] Tumors. These can grow on or under the skin. They can also form along certain nerves, especially the optic (eye) nerve or spinal nerves. Tumors can also form in the brain and other body areas. The tumors are often not cancer. But tumors that grow in certain parts of the body can cause serious problems that need treatment. […] Problems with bone growth. This can happen especially along the spine. This may cause scoliosis. […] Nervous system problems. These may include headaches or seizures. A child may also have developmental delay. This may include problems with learning, reasoning, or behavior. […] Thinking and behavioral problems. Many children with NF1 can have trouble adjusting at school.

    Neurofibromas harmless, soft pink, small lumps that can grow on nerves anywhere in the body. They are most visible in the skin. Most commonly, neurofibromas first appear around adolescence but, by age 30, almost all people with NF1 will have several (and some have hundreds). Over time, neurofibromas may slowly grow in size. It is rare for them to cause any problems; however, some people may have concerns about their appearance. […] Plexiform neurofibromas localised areas where a tangle of extra nerve tissue sits within normal tissues. They can occur anywhere in the body. About five per cent of plexiform neurofibromas cause a major problem with appearance. They almost always develop before birth and most become obvious by two years of age.

    Neurofibromatosis type 1 (NF1) is a genetic condition. It causes benign (not cancerous) tumors to grow in and under the skin, often with bone, hormone, and other problems. Most kids with NF1 have mild symptoms that don’t limit what they can do. Most newborns with neurofibromatosis type 1 have no symptoms, but some have curved lower leg bones. By their first birthday, most children with NF1 have several skin spots, called caf-au-lait („coffee with milk”) spots because of their color. Children with NF1 may be slower to walk, talk, and reach other milestones than most kids. They also may have: bumps in and under the skin (called neurofibromas), a head that looks large for the body, headaches, trouble learning, attention problems and hyperactivity, a shorter height than most children the same age, side-to-side curves in the backbone (scoliosis), curving, thinning, or weakness of the forearms or lower leg bones, freckles in their armpits or in the crease between the belly and hip (groin).

Bone deformities such as abnormal bone development can cause scoliosis (a curved spine) or a bowed leg. Large head and short stature may occur in children who have NF1. They tend to have a larger-than-average head and are typically shorter than average. Learning disabilities including mild learning disability and attention-deficit/hyperactivity disorder (ADHD) as well as speech delay are common in children with NF1.

    Adolescence for both genders may precipitate the development of subcutaneous and cutaneous neurofibromas. Increase in the size of existing neurofibromas and the appearance of new neurofibromas during pregnancy is a frequent observation in women with NF1. […] Scoliosis in NF1 is often mild, but a subset of children younger than 10 years develop a more rapidly progressive form of scoliosis that requires aggressive intervention. […] Although most individuals with neurofibromatosis type 1 (NF1) lead relatively long and healthy lives, the overall life expectancy may be reduced by on average 8 years. The major causes for this increased morbidity and subsequent mortality are hypertension, sequelae of spinal cord lesions, and malignancy.

    Rapid NF1-PN growth and symptom progression are typical during early childhood, but disease progression can occur at any time. […] NF1-PN generally develops at birth or in early childhood, growing most rapidly before 5 years of age. During the early years, NF1-PN typically progresses at the fastest rate, with tumors potentially increasing in volume by 20% to 240% per year. […] As people age, NF1-PN tumor growth usually slows. In adulthood, tumor growth greater than 20% is uncommon, and available data suggests that most increase in size by less than 5% annually. […] People with NF1-PN may experience various symptoms depending on how the tumors affect their nerves. These symptoms may change over time as tumors grow or shrink. […] A 2018 review involving 41 people with NF1-PN looked at how the symptoms associated with these tumors change over time. Over approximately 6.5 years, more people reported symptoms related to pain, motor dysfunction, and bladder and bowel problems.

Children who have NF1 often are below average in height. […] Complications of neurofibromatosis type 1 (NF1) vary, even within the same family. Generally, complications occur when tumors affect nerve tissue or press on internal organs. […] Neurological symptoms. Trouble with learning and thinking are the most common neurological symptoms associated with NF1. Less common complications include epilepsy and the buildup of excess fluid in the brain. […] Skeletal symptoms. Some children have bones that didn’t form as usual. This can cause bowing of the legs and fractures that sometimes don’t heal. NF1 can cause curvature of the spine, known as scoliosis, that may need bracing or surgery.

    Neurofibromatosis type 1 (NF1) is a clinically heterogeneous, neurocutaneous genetic disorder characterized by caf-au-lait spots, iris Lisch nodules, axillary and inguinal freckling, and multiple neurofibromas. […] The clinical features are highly variable, even within the same family. Multiple caf-au-lait macules are found in almost all patients (some at birth and most before the first year). Intertriginous freckling develops starting at 5 years of age. Multiple cutaneous and subcutaneous neurofibromas develop in adults. In older patients, they continue to increase in number and size. Cutaneous neurofibromas do not become malignant. Plexiform neurofibromas (growing along the nerve and its branches) may cause disfigurement, pain, and functional problems and are usually present at birth and may become malignant later in life. Ocular manifestations include optic pathway gliomas and iris hamartomas (Lisch nodules). Optic pathway gliomas usually develop before age 6 years, and rarely progress thereafter. Osteopenia, osteoporosis, bone overgrowth, short stature, macrocephaly, scoliosis, skeletal dysplasia (sphenoid wing, vertebral), and pseudoarthrosis may be present. Other features include hypertension, vasculopathy, intracranial tumors, malignant peripheral nerve sheath tumor (MPNST), and occasionally seizures or hydrocephalus. Intellectual development is usually not severely affected but cognitive deficits and learning difficulties are frequent (50%-75%). The overall cancer risk is higher than the general population (lifetime risk of 10-12% for MPNST, mostly between 20-40 years; increased risk of breast cancer before age 50). […] Overall prognosis is good but significant morbidity is common. MPNST generally has a poor prognosis. Malignancy and vascular disease are the most common causes of early demise.

    Given the many pain-related symptoms and complications in individuals with NF1, it is important to let your doctor know about any pain you have. It is ideal to work with a physician who was expertise in NF1. If your doctor does not have experience with this disease, it may be worthwhile to seek out someone who does. […] Not surprisingly, researchers have found that more severe symptoms, including pain, are associated with diminished quality of life among adults and children with NF1. Further, more severe pain has been found among children who have more symptoms of depression and anxiety. According to questionnaires completed by parents of children with NF1, the children with worse pain have a harder time keeping up with activities of daily living, such as dressing, grooming, and getting along with peers. These research findings seem to suggest that pain has a negative impact on things like emotional functioning and quality of life. However, the relationship seems to work both ways. That is, many people report that their pain feels worse when they feel sad, when the quality of their relationships is poor, or even when they have an overall decrease in life satisfaction.

    Neurofibromatosis type 1 is a progressive disease and, although in some patients the symptoms remain stable, in majority of the patients with the passing time the symptoms escalate. It is impossible to predict the direction of the disease’s progression in an individual patient. Neurofibromatosis type 1 increases the risk of cancerous transformation, especially nervous system tumours. Furthermore interstitial lung diseases, lung cancer, pulmonary hypertension and gastrointestinal tract neoplasms might occur – usually in the adulthood. […] In the presented patient a transformation from neurofibroma to malignant peripheral nerve sheath tumour (MPNST) occurred. Malignant peripheral nerve sheath tumours (MPNST) are aggressive soft tissues sarcomas that take their origin in neural cells. They are characterized by rapid disease progression, high mortality rate, high relapse rate and low response rates to cytotoxic chemotherapy. They remain amongst the most challenging mesenchymal malignancies to treat. In 50% of cases their occurrence is associated with von Reclinghausen’s disease. The prognosis then is poorer than in cases of their spontaneous appearance.

    There is no way to predict who will have a mild case and who will develop more serious symptoms, but the majority of those with NF1 will have minor cases (60%). […] Dermal neurofibromas can be cutaneous (on the skin surface) or subcutaneous (under the skin) and are lumps that are very typical to NF1. Most are not a medical issue, but can cause pain and itching. […] Plexiform neurofibromas are less common, occurring in about 25% of NF patients. They can grow large, and can cause problems such as pressure on nerves and organs. […] Lateral curvature of the spine, known as scoliosis, is common in NF1. In most cases it is mild and appears during the teenage growth spurt. In more severe cases, it appears in early childhood and requires close monitoring. […] Intelligence in NF1 is usually in the normal range, but children may need extra help in school. Learning challenges occur in about 50% of children with NF1.

    Clusters of freckles in unusual places, like the underarm or groin […] Bone problems, such as a curved spine (scoliosis) or curved long bones (such as the legs) […] Learning challenges such as issues with reading or math. […] Larger head size than average […] Shorter height than average. […] Most NF1 tumors are benign (non-cancerous). However, about 10% of people with NF1 may develop a cancerous tumor called a malignant peripheral nerve sheath tumor (MPNST). This type of tumor grows quickly and can spread to other areas. Early detection and treatment are important. […] NF1 is also associated with increased risk of other cancers, such as breast cancer, gastrointestinal tumors (GIST), and sarcomas.

    While less common, some neurofibromatosis tumors can develop into cancer. […] A diagnosis can happen several years after you first have symptoms. Some people dont receive a diagnosis until theyre adults. Thats because neurofibromatosis symptoms appear in stages over time. […] No treatment is necessary if you dont have symptoms or your symptoms dont interfere with your daily life. Your provider will recommend annual or twice-annual checkups to monitor the progress of the condition. […] Neurofibromatosis doesnt usually affect your life expectancy. The location of the tumors can make certain aspects of your daily routine difficult without assistance, like hearing and seeing, for example. Complications can lead to possible life-threatening outcomes, like cancer, if left untreated. […] If you have neurofibromatosis, your provider will schedule regular checkups to monitor your symptoms, usually at six- to 12-month intervals. Schedule an additional appointment if you notice any new or worsening symptoms.
