Ektazja przewodów piersiowych
Diagnostyka i diagnoza

Ektazja przewodów piersiowych to łagodny stan charakteryzujący się poszerzeniem przewodów mlekowych pod brodawką sutkową, często z pogrubieniem ścian i wypełnieniem ich płynem lub gęstą wydzieliną. Diagnostyka opiera się na potrójnej ocenie: badaniu klinicznym, badaniach obrazowych (USG, mammografia, MRI) oraz badaniu histopatologicznym (biopsja cienko- lub gruboigłowa). Ultrasonografia jest metodą z wyboru, gdzie poszerzenie przewodów >2-3 mm, hipoechogeniczne, gładkościenne struktury tubularne sugerują ektazję. Mammografia u kobiet >40 r.ż. może wykazać poszerzone, kręte przewody i rozgałęziające się zwapnienia. W przypadku niejednoznacznych wyników lub podejrzenia złośliwości (np. obwodowa lokalizacja, pogrubienie ścian, hipoechogeniczność otaczającego miąższu) wskazana jest biopsja w celu wykluczenia raka piersi.

Diagnostyka Ektazji Przewodów Piersiowych

Ektazja przewodów piersiowych (mammary duct ectasia) to łagodny stan chorobowy charakteryzujący się poszerzeniem jednego lub większej liczby przewodów mlekowych znajdujących się pod brodawką sutkową. Ściany przewodów mogą ulegać pogrubieniu, a sam przewód może wypełniać się płynem lub zostać zablokowany gęstą, lepką substancją. Chociaż stan ten jest łagodny i nie zwiększa ryzyka wystąpienia raka piersi, jego diagnostyka ma kluczowe znaczenie, gdyż objawy mogą niekiedy przypominać nowotwór piersi.123

Badanie kliniczne

Podstawą procesu diagnostycznego ektazji przewodów piersiowych jest dokładne badanie kliniczne. Lekarz przeprowadza wywiad medyczny, analizując występujące objawy, takie jak wydzielina z brodawki sutkowej, bolesność piersi czy obecność wyczuwalnego guzka. Badanie fizykalne obejmuje ocenę obu piersi, zwracając szczególną uwagę na brodawkę sutkową i otoczkę. Po wstępnej ocenie lekarz pierwszego kontaktu najczęściej kieruje pacjentkę do specjalistycznej poradni chorób piersi, gdzie zostanie ona zbadana przez lekarzy specjalistów lub wykwalifikowany personel pielęgniarski.456

W ramach badania w poradni chorób piersi wykonuje się szczegółową ocenę kliniczną, która jest pierwszym elementem tzw. potrójnej oceny (triple assessment), obejmującej:78

  • Ocenę kliniczną (wywiad i badanie fizykalne)
  • Badania obrazowe (ultrasonografia, mammografia, czasem MRI)
  • Badanie histopatologiczne (biopsja cienkoigłowa lub gruboigłowa)

Badania obrazowe

Diagnostyka obrazowa odgrywa kluczową rolę w rozpoznawaniu ektazji przewodów piersiowych oraz różnicowaniu jej z innymi schorzeniami piersi. Do najczęściej stosowanych metod należą:910

Ultrasonografia piersi

Ultrasonografia (USG) jest obecnie uważana za optymalną metodę obrazowania u pacjentek z podejrzeniem ektazji przewodów piersiowych. Badanie to pozwala lekarzowi na ocenę struktury przewodów mlekowych pod brodawką sutkową i jest wskazane we wszystkich przypadkach wydzieliny z brodawki.1112

W ektazji przewodów piersiowych charakterystyczne cechy w USG obejmują:1314

  • Poszerzone przewody o średnicy przekraczającej 2 mm lub 3 mm w okolicy ampuły
  • Hipoechogeniczne struktury o kształcie tubularnym
  • Gładkościenne przewody bez wewnątrzprzewodowych ubytków wypełnienia

15

Na podstawie badań wykazano, że istnieją istotne różnice w obrazie ultrasonograficznym między łagodną a złośliwą ektazją przewodów. Cechy mogące sugerować złośliwy charakter zmian w USG to:1617

  • Obwodowa lokalizacja poszerzonych przewodów
  • Niewyraźne granice
  • Pogrubienie ścian przewodów
  • Hipoechogeniczność otaczającego miąższu

1819

Mammografia

Mammografia jest często stosowaną metodą diagnostyczną u pacjentek z podejrzeniem ektazji przewodów piersiowych, szczególnie u kobiet po 40. roku życia. Dostarcza obrazów rentgenowskich piersi i może pomóc lekarzowi w ocenie tkanki piersiowej. Diagnostyczna mammografia zapewnia bardziej szczegółowe obrazy określonego obszaru piersi niż standardowa mammografia przesiewowa.2021

W obrazie mammograficznym ektazji przewodów piersiowych można zaobserwować:222324

  • Poszerzone, kręte przewody podotoczkowe
  • Struktury o tubularnym kształcie zorientowane w kierunku brodawki sutkowej
  • Rozgałęziające się zwapnienia

25

Należy jednak zaznaczyć, że w niektórych przypadkach mammografia może nie być konieczna do postawienia diagnozy ektazji przewodów piersiowych, szczególnie u młodszych pacjentek z typowymi objawami.26

Inne metody obrazowania

W diagnostyce ektazji przewodów piersiowych mogą być również stosowane inne metody obrazowania:2728

  • Galaktografia (duktografia) – technika wykorzystująca wsteczne wstrzyknięcie wodnorozpuszczalnego, cieniującego środka kontrastowego do układu przewodów piersiowych. Jest szczególnie przydatna w ocenie niezwapniającej ektazji przewodów piersiowych u kobiet z wydzieliną z brodawki sutkowej.2930
  • Rezonans magnetyczny (MRI) – technologia ta stała się standardem diagnostycznym w chorobach piersi. W obrazach MRI ektazja przewodowa często przedstawia się jako poszerzone struktury tubularne o charakterystycznym wzorze zbieżnym w kierunku brodawki, najczęściej bez wzmocnienia kontrastowego.3132
  • Duktoskopia (fiberduktoskopia) – nowsza metoda, polegająca na wprowadzeniu miniaturowego endoskopu do przewodu mlekowego w celu bezpośredniej wizualizacji wnętrza przewodu. Jest to mniej inwazyjny sposób oceny przyczyn wydzieliny z brodawki sutkowej.3334

Badania histopatologiczne

W niektórych przypadkach, zwłaszcza gdy wyniki badań obrazowych są niejednoznaczne lub sugerują złośliwy charakter zmian, konieczne jest wykonanie biopsji w celu wykluczenia raka.3536

Metody pobierania materiału do badania histopatologicznego obejmują:3738

  • Biopsja gruboigłowa piersi – pobranie za pomocą igły biopsyjnej małej próbki tkanki do badania mikroskopowego; może być wykonana pod kontrolą USG
  • Biopsja cienkoigłowa (FNA – Fine Needle Aspiration) – pobranie próbki komórek za pomocą cienkiej igły i strzykawki w celu oceny mikroskopowej
  • Badanie cytologiczne wydzieliny z brodawki sutkowej (NDC – Nipple Discharge Cytology) – analiza komórek obecnych w wydzielinie z brodawki, szczególnie jeśli ma ona charakter krwisty

W obrazie histopatologicznym ektazji przewodów piersiowych charakterystyczne cechy to:3940

  • Poszerzenie przewodów
  • Zapalenie okołoprzewodowe i/lub włóknienie
  • Obecność histiocytów piankowatych w naciekach zapalnych
  • Światła przewodów mogą być wypełnione zagęszczonymi wydzielinami i komórkami zapalnymi
  • Tkanka ziarninowa
  • Włóknienie

Diagnostyka różnicowa

Ektazja przewodów piersiowych może przypominać inne schorzenia piersi, zarówno łagodne, jak i złośliwe, dlatego ważna jest dokładna diagnostyka różnicowa.4142

Różnicowanie z zapaleniem około-przewodowym

Objawy kliniczne ektazji przewodów piersiowych nakładają się z innym łagodnym stanem zapalnym znanym jako zapalenie około-przewodowe (periductal mastitis), które występuje w obrębie kompleksu brodawka-otoczka. Zapalenie okołoprzewodowe często wymaga leczenia antybiotykami, dlatego ważne jest prawidłowe rozpoznanie.4344

Różnicowanie z nowotworem piersi

Główną rolą lekarza zajmującego się pacjentkami z ektazją przewodów piersiowych jest wykluczenie nowotworu złośliwego piersi. Cechy, które powinny wzbudzić podejrzenie złośliwości i skłonić do wykonania biopsji, to:4546

  • Jednostronne (asymetryczne) poszerzenie przewodów bez potwierdzonej stabilności w poprzednich badaniach
  • Lokalizacja poza obszarem podotoczkowym
  • Hipoechogeniczna zawartość wewnątrzprzewodowa
  • Nieregularność lub niejasność ścian przewodów
  • Obecność litego guza miąższowego
  • Pojedynczy poszerzony przewód (rzadki typ asymetrycznej ektazji przewodów)

47

W przypadku, gdy występuje obwodowa, niewyraźnie odgraniczona ektazja przewodów z pogrubieniem ścian przewodów i towarzyszącą hipoechogenicznością otaczającej tkanki piersiowej w badaniu USG, należy rozważyć możliwość złośliwości, takiej jak rak in situ, i radiolodzy nie powinni wahać się zalecić natychmiastowej biopsji.4849

Znaczenie interdyscyplinarnego podejścia

Diagnoza ektazji przewodów piersiowych wymaga interdyscyplinarnego podejścia, korelującego badanie kliniczne z odpowiednim obrazowaniem w celu identyfikacji podejrzanych przypadków. Żadne pojedyncze badanie nie jest wystarczające do postawienia diagnozy ektazji przewodów piersiowych. Prezentacja kliniczna może być zmienna, a samo obrazowanie nie pozwala na wiarygodne odróżnienie jej od łagodnych stanów, takich jak brodawczaki, czy nawet złośliwości w niektórych przypadkach.5051

W przypadku rozbieżności między klinicznymi, radiologicznymi i patologicznymi wynikami, odpowiednio zaplanowane chirurgiczne wycięcie pomaga w prawidłowej diagnozie i leczeniu.52

Podsumowanie diagnostyczne

Diagnostyka ektazji przewodów piersiowych opiera się na kompleksowym podejściu, które obejmuje:5354

  • Dokładne badanie kliniczne piersi
  • Ultrasonografię brodawki i otoczki
  • Mammografię
  • W wybranych przypadkach dodatkowe badania obrazowe (MRI, galaktografia, duktoskopia)
  • Badania histopatologiczne, gdy istnieje podejrzenie złośliwości

Ważne jest, aby pamiętać, że ektazja przewodów piersiowych nie zwiększa ryzyka wystąpienia raka piersi. Niemniej jednak, ze względu na podobieństwo objawów do innych poważniejszych schorzeń, w tym raka piersi, istotne jest, aby pacjentki zgłaszały się do lekarza w celu badania piersi w przypadku zauważenia jakichkolwiek zmian.5556

Wczesne wykrycie i właściwa diagnostyka mają kluczowe znaczenie dla zminimalizowania powikłań i zapewnienia najskuteczniejszego postępowania w przypadku tego schorzenia.57

    Duct ectasia, also known as mammary duct ectasia, is a benign (non-cancerous) breast condition that occurs when a milk duct in the breast widens and its walls thicken. This can cause the duct to become blocked and lead to fluid build-up. […] Often, this condition causes no symptoms and is found when a biopsy (removal of small pieces of breast tissue to be checked with a microscope) is done for another breast problem. […] Less often, duct ectasia may cause a nipple discharge, which is often sticky and thick. The nipple and nearby breast tissue may be tender and red, and the nipple may be pulled inward. Sometimes scar tissue around the abnormal duct causes a hard lump that may be confused with cancer. A mammogram and/or breast ultrasound may be done to learn more about the changed part of your breast. […] Duct ectasia does not increase your risk for breast cancer.

    Mammary duct ectasia, or breast duct ectasia, occurs when a milk duct becomes blocked. […] The American Cancer Society advise that mammary duct ectasia is a noncancerous, or benign, condition that does not increase the risk of breast cancer. […] To diagnose mammary duct ectasia, a doctor will ask questions about a persons symptoms and review their medical history. They will usually also perform a breast exam. […] The doctor may then recommend one or more of the following tests: a mammogram, which is an X-ray of the breast; an ultrasound scan of the breast tissue; a biopsy, in which the doctor takes a sample of breast tissue using a thin needle and sends it to a laboratory for examination under a microscope; analyzing a sample of nipple discharge, especially if it contains blood. […] The symptoms of mammary duct ectasia can be similar to some of those of breast cancer, so it is important for people to see a doctor for a breast examination.

    Mammary duct ectasia is a benign condition where there is dilation of the large ducts in the breasts. Ectasia means dilation. There is inflammation in the ducts, leading to intermittent discharge from the nipple. The discharge may be white, grey or green. […] Mammary duct ectasia may present with: Nipple discharge, Tenderness or pain, Nipple retraction or inversion, A breast lump (pressure on the lump may produce nipple discharge). […] It may be picked up incidentally on a mammogram, leading to further assessment and investigations. […] The initial priority is to exclude breast cancer, as they can present in similar ways. This involves triple assessment with: Clinical assessment (history and examination), Imaging (ultrasound, mammography and MRI), Histology (fine needle aspiration or core biopsy).

    https://patient.info/doctor/mammary-duct-ectasia-and-periductal-mastitis
    Mammary duct ectasia is a benign breast disease that can mimic invasive carcinoma clinically. The process that causes the mammary duct ectasia is still being debated but histologically it is characterised by dilation of major ducts in the subareolar region. The breast ducts contain eosinophilic granular secretions and foamy histiocytes. The secretions may undergo calcification and this may be the presenting sign. […] Imaging will be required. There are no solid guidelines about which clinical or radiological features accurately distinguish malignancies from lesions with a benign aetiology. Non-invasive methods are preferable. – and breast ultrasound enables the visualisation of the ductal structure and intraductal causes of pathological nipple discharge, and facilitates a subsequent imaging-guided percutaneous biopsy. Higher resolutions and the introduction of Doppler facilitate the differentiation between benign and malignant lesions. Follow-up with regular mammography is recommended. […] A mammogram is a useful screening tool, particularly in older women. It is especially sensitive in picking up microcalcification and should be performed whenever complicated, malignant and uncommon forms of mastitis are suspected.

    Mammary duct ectasia represents a benign condition characterized by the dilatation of the mammary ducts. The diagnosis can be clinically challenging due to its complex and diversified symptoms, but also because in some cases it can mimic breast cancer. […] Therefore, a proper approach is to employ imaging methods to establish a diagnosis of mammary duct ectasia primarily mammography, galactography, ultrasound, and magnetic resonance imaging. […] On mammography (which provides X-ray images of the breast), mammary duct ectasia is seen as one or more tubular structures that are oriented to the nipple. […] Non-calcifying mammary duct ectasia in women with nipple discharge is better evaluated by galactography, which is a technique that uses a retrograde injection of water-soluble radiopaque contrast into the breast duct system.

[…] Mammary duct ectasia is common in women aged 5060 years who are in the perimenopausal period. Normal breast ducts measure 2.53 mm in diameter with no solid intraductal lesion and no associated breast mass. The presenting symptoms are nipple discharge, nipple retraction, and breast pain or tenderness. […] Duct changes may be seen as an associated feature of breast malignancy. The common appearances on breast ultrasound are dilated ducts seen along a mass that has the morphological features of malignancy. A mass lesion and a dilated duct from the nipple to the mass indicates the site of origin of the duct carcinoma along the ductal epithelium. These are diagnostic features and confirm a radiopathological diagnosis.

    Mammary duct ectasia is the abnormal widening of one or more breast ducts to greater than 2 mm diameter, or 3 mm at the ampulla. It can be due to benign or malignant processes. […] Ductal ectasia is often asymptomatic, especially when benign. However, patients with ductal ectasia may present with nonspecific breast symptoms: nipple discharge, nipple retraction, pain/tenderness, palpable mass. […] Benign duct ectasia is characterized by chronic inflammatory and fibrotic changes. […] Intraductal malignancy can also cause duct ectasia. […] Most treatments are aimed at symptom relief and excluding more malicious pathologies. If there is a mastitis element, antibiotics may be considered. […] A unilateral (asymmetric) mammographic finding of duct ectasia without demonstrated stability on prior studies warrants further evaluation with ultrasound. Features that on ultrasound should raise suspicion for malignancy include nonsubareolar location, hypoechoic intraluminal contents, ductal wall irregularity or indistinctness, or solid parenchymal mass. […] A solitary dilated duct, a rare type of asymmetric duct ectasia, is suspicious for malignancy and biopsy should be considered.

    Duct ectasia is, however, a rare occurrence in accessory breast and only a few cases have been previously reported. […] A 38-year-old female, presented with marked and extensive duct ectasia involving almost whole of the right breast parenchyma and bilateral accessory axillary breasts with infrequently observed findings on mammography and ultrasonography. […] This case report highlights the imaging features of duct ectasia involving the accessory axillary breasts which is a rare occurrence. Awareness of imaging features of this entity may help in early diagnosis to allow adequate management, and also, to prevent its complications like the formation of abscesses and fistulae. […] Diagnosis is usually clinical; however, imaging is required for proper evaluation of the disease process. Mammographic appearance of duct ectasia depends upon the overall density of breast parenchyma and the degree of dilatation of ducts. On mammography, the ectatic ducts appear as dense serpentine tubular structures converging towards the nipple.
