Modzele i pęcherze – Epidemiologia

Modzele i pęcherze
Epidemiologia

Modzele i pęcherze stanowią jedne z najczęstszych schorzeń stóp, z częstością występowania w populacji ogólnej od 14% do 48%, a w klinikach podologicznych odpowiadają za około 46% zaburzeń stóp. Występują częściej u osób starszych (20-65% w wieku ≥65 lat) oraz u kobiet, co wiąże się z noszeniem nieodpowiedniego obuwia. Czynniki ryzyka obejmują nieprawidłowo dopasowane buty, deformacje stóp (np. palce młotkowate, buniony), aktywność zawodową wymagającą długotrwałego obciążenia stóp oraz choroby współistniejące, takie jak cukrzyca i zaburzenia krążenia. Modzele i pęcherze mogą prowadzić do znacznego dyskomfortu, ograniczenia mobilności oraz powikłań, zwłaszcza u pacjentów z cukrzycą, gdzie ryzyko infekcji i owrzodzeń jest istotne. Diagnostyka opiera się na badaniu klinicznym, a w razie potrzeby na obrazowaniu rentgenowskim w celu oceny deformacji kostnych.

Epidemiologia modzeli i pęcherzy

Modzele i pęcherze należą do najczęstszych schorzeń stóp na świecie, występujących u znacznej części populacji. Badania epidemiologiczne pokazują, że częstość występowania tych zmian waha się w szerokim zakresie od 14% do 48% populacji ogólnej.¹² W klinikach podologicznych modzele i pęcherze stanowią około 46% wszystkich zaburzeń stóp, dotykając około 9,2 miliona Amerykanów, co przekłada się na około 38 przypadków na 1000 osób.³

W dużych badaniach epidemiologicznych wykazano, że ponad połowa (57%) z 76 475 osób zgłaszających się do poradni dermatologicznej lub ogólnej miała jakąś chorobę stóp. W przeglądzie 392 pacjentów uczęszczających do australijskiej kliniki podologicznej odnotowano, że najczęściej występującymi problemami były zmiany paznokci, modzele i pęcherze.⁴ W badaniu oceniającym populację pacjentów leczonych przez brytyjskich podologów stwierdzono, że modzele i pęcherze stanowiły najczęściej występujące problemy (26%), będąc jednocześnie najczęstszym typem leczenia wykonywanym przez przedstawicieli tej profesji (19%) w typowym dniu pracy.⁵

Różnice demograficzne w występowaniu modzeli i pęcherzy

Badania wykazują istotne różnice w częstości występowania modzeli i pęcherzy w zależności od czynników demograficznych:

Wiek: Częstość występowania modzeli i pęcherzy zwiększa się wraz z wiekiem, szczególnie u osób starszych. Badania pokazują, że 20-65% osób w wieku 65 lat lub starszych cierpi na hiperkeratotyczne zmiany stóp, w tym modzele i pęcherze.⁶ Jest to związane z utratą ochronnej poduszki tłuszczowej (zanik poduszki tłuszczowej), co może zwiększać częstość występowania bolesnych modzeli.⁷
Płeć: Kobiety są częściej dotknięte modzelami i pęcherzami niż mężczyźni, co przypisuje się głównie noszeniu nieodpowiednich, często modnych butów.⁸⁹ Badania wykazały, że zarówno kobiety, jak i mężczyźni w podeszłym wieku noszą buty zbyt wąskie dla swoich stóp, a kobiety dodatkowo noszą buty krótsze niż długość ich stóp, co sprzyja powstawaniu modzeli i pęcherzy.¹⁰
Pochodzenie etniczne: Badania epidemiologiczne wykazały znaczące różnice w częstości występowania modzeli wśród różnych grup etnicznych. Amerykanie pochodzenia afrykańskiego mieli znacząco wyższy wskaźnik modzeli i pęcherzy w porównaniu z białymi nie-Hiszpanami i Portorykańczykami (70% vs 58% vs 34,1%).¹¹ Osoby o ciemniej pigmentowanej skórze są bardziej podatne na rozwój modzeli.¹² Czarnoskórzy zgłaszają modzele i pęcherze o 30% częściej niż osoby białe.¹³

Czynniki wpływające na występowanie

Na częstość występowania modzeli i pęcherzy wpływa szereg czynników, z których najważniejsze to:

Nieprawidłowo dopasowane obuwie: Ciasne lub źle dopasowane buty są uważane za główną przyczynę powstawania większości modzeli i pęcherzy.¹⁴ Zbyt wąskie lub ciasne obuwie powoduje zwiększone tarcie i ucisk na skórę, co prowadzi do powstawania zgrubień.¹⁵¹⁶
Deformacje stóp: Osoby z wyraźnymi wystającymi kośćmi, cienką skórą lub jakimikolwiek deformacjami palców lub stóp są bardziej narażone na powstawanie modzeli i pęcherzy.¹⁷ Buniony, palce młotkowate i inne nieprawidłowości kostne zwiększają ryzyko rozwoju tych zmian.¹⁸
Aktywność zawodowa i fizyczna: Około 18% pracowników doświadcza bolesnych modzeli i pęcherzy w wyniku ciągłego obciążenia stóp.¹⁹ Osoby wykonujące zawody wymagające długotrwałego stania, jak pielęgniarki, pracownicy handlu detalicznego czy budownictwa, są szczególnie narażone na powstawanie modzeli.²⁰
Problemy zdrowotne: Cukrzyca jest czynnikiem ryzyka dla powstawania modzeli.²¹ Osoby z cukrzycą lub problemami z krążeniem w stopach są szczególnie narażone na powikłania związane z modzelami i pęcherzami.²²

Nadzór i monitorowanie

Nadzór nad występowaniem modzeli i pęcherzy jest istotny z kilku powodów:²³²⁴

Modzele i pęcherze, choć zwykle nie są poważne, mogą prowadzić do znacznego dyskomfortu i bólu, wpływając na mobilność i jakość życia pacjentów
U osób z cukrzycą lub problemami z krążeniem mogą prowadzić do poważniejszych powikłań, w tym infekcji i owrzodzeń
Nieleczone modzele i pęcherze mogą powiększać się, prowadząc do pęknięć skóry i potencjalnych infekcji

Systemy klasyfikacji i oceny

W celu standaryzacji monitorowania modzeli i pęcherzy opracowano różne systemy klasyfikacji:²⁵

Stopniowany system klasyfikacji został opracowany w ramach badania obejmującego 1700 pacjentów
Systemy klasyfikacji podologicznej rozszerzyły swoje stopniowanie do obejmowania stopni 5 i 6, gdzie ostatni odnosił się do przerwania naskórka
Fotograficzna ocena jest powszechną metodą oceny zmian, jednak wiąże się z trudnościami w różnicowaniu podobnych zmian bez bezpośredniej palpacji

Skala nominalna z czterema stopniami została oparta na hipotezie obejmującej etapy pokazujące krytyczny charakter zmian z deformacją palucha koślawego i bez niej. System ten nie różnicuje jednak innych patologii, takich jak ciała obce, zmiany włókniste, torbiele inkluzyjne, zapalenie kaletki, skutki uszkodzonych stawów śródstopno-paliczkowych, HPV i nowotwory.²⁶

Znaczenie wczesnej identyfikacji i interwencji

Wczesna identyfikacja modzeli i pęcherzy jest kluczowa dla zapobiegania powikłaniom:²⁷²⁸

Wczesna diagnoza i opieka mogą pomóc w łagodzeniu objawów zanim się nasilą
Zapobieganie powikłaniom, takim jak infekcje lub owrzodzenia skóry, jest szczególnie ważne dla osób z cukrzycą lub problemami z krążeniem
Osoby z cukrzycą powinny regularnie badać swoje stopy w celu identyfikacji wszelkich problemów i natychmiast zgłaszać się po pomoc medyczną w razie ich wystąpienia

Diagnozy modzeli i pęcherzy dokonuje się na podstawie wyglądu i wywiadu medycznego.²⁹ Lekarz przeprowadzi dokładne badanie fizyczne, oceniając teksturę skóry, grubość i obecność jakichkolwiek stwardniałych obszarów charakterystycznych dla tych schorzeń. W przypadku niepewności co do przyczyny zmian skórnych lub w celu oceny potencjalnych problemów podstawowych, takich jak deformacje kości, mogą być zalecane dodatkowe narzędzia diagnostyczne, takie jak prześwietlenia rentgenowskie.³⁰

Zarządzanie i leczenie

Zarządzanie i leczenie modzeli i pęcherzy wymaga wielokierunkowego podejścia, które koncentruje się na łagodzeniu objawów, ustaleniu mechanicznej etiologii, opracowaniu planu leczenia obejmującego wyściełanie i modyfikację obuwia oraz rozważenie operacji, jeśli środki zachowawcze zawiodą.³¹

Leczenie zachowawcze

Większość przypadków modzeli i pęcherzy można leczyć zachowawczo:³²³³

Stosowanie odpowiednio dopasowanego obuwia to podstawa leczenia – większość zmian mechanicznych można zachowawczo leczyć przy użyciu odpowiedniego obuwia
Wkładki ortopedyczne lub wkładki mogą zapewnić dodatkowe wsparcie i złagodzić punkty nacisku na stopę
Utrzymywanie skóry stóp dobrze nawilżonej jest prostym, ale skutecznym środkiem zapobiegawczym

Interwencje specjalistyczne

W przypadku utrzymujących się lub bolesnych modzeli i pęcherzy zaleca się interwencje specjalistyczne:³⁴³⁵

Podolodzy stosują oczyszczanie i przycinanie w celu bezpiecznego usuwania zgrubiałej skóry i łagodzenia punktów nacisku
Osoby mogą skorzystać z obuwia ortopedycznego przepisanego przez podologa, które pomaga w redystrybucji nacisku i zapobieganiu nawrotom modzeli i pęcherzy
W przypadku uporczywych lub ciężkich przypadków modzeli i pęcherzy mogą być zalecane leki na receptę, takie jak retinoidy miejscowe lub kortykosteroidy
Opcje chirurgiczne, w tym operacja usunięcia modzela lub pęcherza, mogą być rozważane w przypadkach, gdy środki zachowawcze okażą się niewystarczające

Specjalne grupy pacjentów

Osoby z cukrzycą lub problemami z krążeniem wymagają szczególnej uwagi:³⁶³⁷³⁸

Pacjenci z cukrzycą lub złym krążeniem są narażeni na większe ryzyko powikłań ze strony modzeli i pęcherzy
Osoby te powinny regularnie sprawdzać swoje stopy i szukać podologicznej opieki w celu leczenia i zarządzania modzelami i pęcherzami
Nieleczone modzele i pęcherze mogą prowadzić do poważnych infekcji i owrzodzeń u tych pacjentów

Szczególną grupą są także osoby starsze, u których zanik poduszki tłuszczowej zwiększa ryzyko powstawania bolesnych modzeli.³⁹ W tej grupie często stosuje się minimalnie inwazyjne procedury w gabinecie, które polegają na znieczuleniu obszaru i usunięciu małego kawałka kości leżącej u podstawy modzela.⁴⁰

Znaczenie dla zdrowia publicznego

Modzele i pęcherze, choć często postrzegane jako drobne dolegliwości, mogą mieć istotny wpływ na zdrowie publiczne:⁴¹⁴²

Stanowią częsty problem stóp, wpływający na znaczną część populacji
Mogą powodować istotny ból, dyskomfort i ograniczenie mobilności, co wpływa na jakość życia
Zarządzanie modzelami i pęcherzami ma niski stosunek kosztów do korzyści, co prowadzi do zmniejszenia priorytetyzacji w opiece zdrowotnej

Badanie MFPDI (Manchester Foot Pain and Disability Index) wykazało, że ból stóp związany z modzelami wzrasta z wiekiem, płeć i typ modzela wykazują pewien istotny związek z bólem stóp, a nie ma dowodów sugerujących, że rozmiar modzela ma jakikolwiek wpływ na upośledzający ból stóp.⁴³

Edukacja i profilaktyka

Kluczowe znaczenie ma edukacja pacjentów i profilaktyka:⁴⁴⁴⁵

Edukacja na temat odpowiedniego obuwia – podstawą zapobiegania powstawaniu modzeli i pęcherzy jest wybór obuwia, które priorytetowo traktuje komfort i odpowiednie dopasowanie
Świadomość czynników ryzyka i wczesnych objawów może pomóc w zapobieganiu rozwojowi poważnych zmian
Regularne badania stóp, szczególnie u osób z grupy ryzyka, mogą pomóc w identyfikacji i wczesnym leczeniu modzeli i pęcherzy

Rola specjalistów w zarządzaniu modzelami i pęcherzami

Specjaliści opieki zdrowotnej odgrywają kluczową rolę w zarządzaniu modzelami i pęcherzami:⁴⁶⁴⁷

Podolodzy są często pierwszą linią opieki dla pacjentów z modzelami i pęcherzami, oferując specjalistyczne leczenie i porady
Ogólne leczenie modzeli i pęcherzy może być prowadzone przez specjalistów zdrowia stóp, którzy mogą przywrócić stopy do zdrowego, komfortowego i szczęśliwego stanu
Specjaliści mogą również pomóc w identyfikacji i leczeniu podstawowych przyczyn modzeli i pęcherzy, takich jak deformacje stóp lub problemy z chodem

Właściwe zarządzanie modzelami i pęcherzami wymaga kompleksowego podejścia, które uwzględnia nie tylko leczenie istniejących zmian, ale także zapobieganie ich nawrotom poprzez odpowiednie środki profilaktyczne i edukację pacjentów.⁴⁸ W większości przypadków modzele i pęcherze ustąpią przy odpowiednim leczeniu zachowawczym, co czyni właściwą diagnozę i leczenie niezbędnymi.⁴⁹

#1 Corns – StatPearls – NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK470374/
Corns typically result from repeated accumulated mechanical trauma as well as other contributing factors like ill-fitting footwear, the presence of bony prominences (foot deformity), and certain physical activities. They are most common on the feet: on the dorsum of the toes, in the last interdigital web space, as well as on the soles of the feet. […] The incidence of corns on the feet has been reported to be ranging anywhere from 14% to 48%. Individuals with darkly pigmented skin are more prone to developing corns. They have been reported to affect older age groups with a slight female predominance due to wearing narrow shoes. The elderly are also subject to loss of the protective fat pad cushioning, called fat pad atrophy, which can increase the incidence of painful corn.

https://emedicine.medscape.com/article/1089807-overview
Corns are one of the most common foot conditions in the United States, particularly amongst older patients. It is a common disorder because of the frequency of usage of occlusive footwear and participation in repetitive activities, such as running. […] Corns are common worldwide. Any weight-bearing human is susceptible to the development of corns. […] An epidemiological study evaluating the prevalence of foot conditions amongst a diverse sample of adults from the northeastern United States revealed a significant difference in rates of corns amongst ethnic groups. African Americans had a significantly higher rate of corns and calluses compared with non-Hispanic white and Puerto Rican participants (70% vs 58% vs 34.1%). […] Amongst elderly populations, both men and women have been reported to wear shoes too narrow for their feet. Women have been reported to wear shoes that are also shorter than their feet. Both narrow and short footwear can lead to the development of corns, in addition to foot deformities. They are more common in women than in men because of this use of occlusive and poorly fitted footwear.

#14 Corns and Calluses: Causes, Prevention and Treatment
https://patient.info/foot-care/corns-and-calluses
Corns and calluses on the feet are thickened areas of skin that can become painful. […] The common causes of rubbing and pressure are tight or ill-fitting shoes which tend to cause corns on the top of the toes and side of the little toe. […] Corns and calluses are more likely to develop if you have very prominent bony toes, thin skin, or any deformities of the toes or feet which cause the skin to rub more easily inside shoes. […] Tight or ill-fitting shoes are thought to be the main cause of most corns and calluses. […] Correcting poor footwear will reduce any rubbing or repeated friction on your skin. […] If you have had a corn or callus pared away, a recurrence will usually be prevented by wearing good footwear. […] A podiatrist can advise you about this.
#15 Corns and Calluses Resulting from Mechanical Hyperkeratosis | AAFP
https://www.aafp.org/pubs/afp/issues/2002/0601/p2277.html
The formation of corns and calluses can be caused by mechanical stresses from faulty footgear (the wearing of poorly fitting shoes), abnormal foot mechanics (deformity of the foot exerting abnormal pressure), and high levels of activity. […] Corns and calluses result from hyperkeratosis, a normal physiologic response of the skin to chronic excessive pressure or friction. […] Most lesions can be managed conservatively by the use of properly fitting shoes and padding to redistribute mechanical forces. […] Symptoms may be severe enough to seriously affect a person’s gait and choice of footgear or activities. […] Most corns and calluses will resolve with appropriate conservative treatment, making the proper diagnosis and treatment essential. […] Hyperkeratosis is a normal protective response of the skin, which becomes pathologic when the callus or corn grows so large that it becomes the source of symptoms.

https://cls.health/specialties/podiatry/foot-corn-and-callus-removal/
Every year, millions of people find themselves dealing with the discomfort of corns and calluses, those persistent patches of thickened, hardened skin that crop up wherever our bodies endure excessive rubbing and stress. […] They develop most frequently on the feet due to constant contact with shoes, corns and calluses are a common yet misunderstood issue. […] While they might seem like minor annoyances, without proper management, they can lead to significant pain and, in some cases, more severe foot problems, especially in individuals with diabetes or circulatory issues. […] The primary cause of corns and calluses is repeated friction and pressure, often resulting from one of the following: […] Ill-fitting Shoes: Wearing shoes that do not fit properly often causes significant friction and pressure on the feet.

https://innovationmedgroup.com/podiatry/corns-calluses/
Corns and calluses may get bigger or lead to an infection. […] You are more likely to develop corns and calluses if you have a foot condition affecting normal alignment, such as a bunion, hammertoe, or arthritis. […] Corns and calluses can get infected, leading to more severe pain that may affect your mobility. Foot infections are especially problematic for people with diabetes. […] If you have diabetes, you need diabetic foot care from the skilled podiatrists at Innovation Medical Group to treat your corns and calluses to prevent infections and other foot problems.
#19 9 Corns and calluses, symptoms, prevention questions
https://bodytonicclinic.co.uk/corns-and-calluses/
Feet get put through the works! From the moment you get out of bed until you next sit down, the feet are under constant stress and pressure. No wonder 18% (Springett et al., 2003) of workers experience painful calluses and corns. […] Corns and calluses are caused by an increase in mechanical pressure and the body responding to protect the area under pressure. Common increases in mechanical pressure include; Wearing high heels, Wearing unsupportive shoes, Not wearing socks, Heavy weight lifting, Playing musical instruments. […] As you can see, these two conditions arenât so different and thatâs why a foot health specialist should be consulted to determine the correct and most effective treatment. A foot health specialist can use a detailed history, visual and hands on assessment to determine what is happening, what has caused this and most importantly, how to treat and prevent this from returning. The key aspect of seeing a foot health specialist is that they can rule out other causes like warts, neuromas or gout.
#20 Corn Removal Surgery & Callus Treatment | CLS Health
https://cls.health/specialties/podiatry/foot-corn-and-callus-removal/
Not Wearing Socks: Engaging in activities without proper footwear, including socks, increases skin soreness and pressure. […] Foot Deformities: People with foot abnormalities, such as hammertoes or bunions, are more prone to developing corns and calluses due to increased friction against their footwear. […] Repetitive Activities: Sports like running, basketball, or soccer and jobs requiring prolonged standing, such as nursing, retail, or construction, often lead to calluses from constant friction and pressure on the feet. […] The diagnosis of corns and calluses typically begins with a thorough physical examination by a healthcare professional. […] During the examination, the doctor evaluates the skins texture, thickness, and the presence of any hardened areas that characterize these conditions.
#21 Corns and calluses: What’s the difference and how can I treat them?
https://www.medicalnewstoday.com/articles/172459
For calluses specifically, diabetes is also a risk factor. […] If the corn or callus is very painful, or if the person has diabetes, fragile skin, or circulatory problems, it is best to consult a doctor or a podiatrist who specializes in foot care. […] A person should never try to remove a corn or callus without medical supervision, especially if they also have diabetes or other underlying conditions. […] A doctor will usually recommend removal surgery only if the cause of the lesion is in the person’s bone structure, such as from a hammer toe or bunion or in some cases of a plantar callus. […] With treatment, corns and calluses may fade away, but without lifestyle or footwear changes, they may return.
#22 Corns and calluses: What’s the difference and how can I treat them?
https://www.medicalnewstoday.com/articles/172459
Corns and calluses are hard, painful areas of skin that often develop on the feet in response to pressure or friction. […] The lesions are more common among people who wear ill-fitting shoes, have sweaty feet, or stand for long periods each day. […] They affect women more than men and more African American and Puerto Rican people than non-Hispanic white people. […] Calluses and corns are not usually harmful, but sometimes they may lead to irritation, infections, or ulcerations of the skin, especially among people with diabetes or poor circulation in the feet. […] The primary risk factor for both corns and calluses is any pressure or friction on the skin. […] Additional risk factors include older age, joint diseases, other foot problems like bunions or hammer toe, walking a lot on flat surfaces, or having flat feet.

The management of plantar corns and callus has a low cost-benefit with reduced prioritisation in healthcare. […] While photography offers a common method for assessing wounds, no published evaluation has been applied to plantar forefoot corns and callus. […] Problems associated with photographic assessment involves trying to differentiate similar lesions without the benefit of direct palpation. […] A graded classification system came about as part of a study involving 1700 patients. […] Podiatric classification systems have been cited without reliability studies and extended their grading to include grades 5 and 6, where the latter related to epidermal breakdown. […] The hypothesis upon which four nominally graded options for corns and callus were based involved staging to show the critical nature of lesions with and without hallux valgus deformity.

Corns and calluses form when the skin is exposed to excessive pressure or friction. […] Corns and calluses can be a medical risk if your circulation or nerves are compromised, such as diabetes complications. […] Corns and calluses are usually the result of friction and pressure against the skin. […] If you have diabetes and/or neuropathy, you should have our doctors take a look at your corns or calluses. These conditions can make it difficult for corns and calluses to heal, and you’re at a higher risk of cuts, infections, and sores. […] If they keep coming back, it’s probably time to have them checked by our doctors. This may be a sign of an underlying problem that we can help you figure out.

While no evidence of staging for epidermal thickening exists in the literature, skin that blisters following shoe rub can alter with epidermal thickening. […] It is acknowledged that while more options might allow for easier classification not all lesions would be possible to classify into four categories. […] Classification does not differentiate other pathology such as foreign bodies, fibrous changes within the DEJ, inclusional cysts, bursae, effects of disrupted metatarsophalangeal joints, HPV and neoplasia. […] Reliability with observation within health must be considered important when the impact of the model used is sensitive enough to make a difference.

Not Wearing Socks: Engaging in activities without proper footwear, including socks, increases skin soreness and pressure. […] Foot Deformities: People with foot abnormalities, such as hammertoes or bunions, are more prone to developing corns and calluses due to increased friction against their footwear. […] Repetitive Activities: Sports like running, basketball, or soccer and jobs requiring prolonged standing, such as nursing, retail, or construction, often lead to calluses from constant friction and pressure on the feet. […] The diagnosis of corns and calluses typically begins with a thorough physical examination by a healthcare professional. […] During the examination, the doctor evaluates the skins texture, thickness, and the presence of any hardened areas that characterize these conditions.
#31 Corns and Calluses Resulting from Mechanical Hyperkeratosis | AAFP
https://www.aafp.org/pubs/afp/issues/2002/0601/p2277.html
Abnormal mechanical stresses on the skin will result in the formation of an accumulation of several layers of the horny layer of epithelium (hyperkeratosis). […] Abnormal mechanical stresses can result from a variety of intrinsic factors (bony prominences or hammertoe deformities) or extrinsic factors (tight shoes, irregularities within the shoe, or high activity levels). […] As mechanical stresses on the skin increase, the body attempts to protect irritated skin by forming a hyperkeratotic lesion, such as a corn or a callus; however, this lesion will increase the pressure in a tight shoe, thus creating a vicious cycle: increased pressure increases the formation of corns or calluses, which further increases the pressure. […] The principles of treatment should be to (1) provide symptomatic relief; (2) determine the mechanical etiology; (3) formulate a treatment plan that includes padding and modification of footwear; and (4) consider surgery if conservative measures fail. […] Most mechanical lesions can be conservatively managed with an adequate shoe. […] Surgery should concentrate on correcting the abnormal mechanical stresses and should only be considered after conservative measures have failed.
#32 Corns and Calluses Resulting from Mechanical Hyperkeratosis | AAFP
https://www.aafp.org/pubs/afp/issues/2002/0601/p2277.html
The formation of corns and calluses can be caused by mechanical stresses from faulty footgear (the wearing of poorly fitting shoes), abnormal foot mechanics (deformity of the foot exerting abnormal pressure), and high levels of activity. […] Corns and calluses result from hyperkeratosis, a normal physiologic response of the skin to chronic excessive pressure or friction. […] Most lesions can be managed conservatively by the use of properly fitting shoes and padding to redistribute mechanical forces. […] Symptoms may be severe enough to seriously affect a person’s gait and choice of footgear or activities. […] Most corns and calluses will resolve with appropriate conservative treatment, making the proper diagnosis and treatment essential. […] Hyperkeratosis is a normal protective response of the skin, which becomes pathologic when the callus or corn grows so large that it becomes the source of symptoms.
#33 Corns and Calluses: Causes, Prevention and Treatment
https://patient.info/foot-care/corns-and-calluses
Corns and calluses on the feet are thickened areas of skin that can become painful. […] The common causes of rubbing and pressure are tight or ill-fitting shoes which tend to cause corns on the top of the toes and side of the little toe. […] Corns and calluses are more likely to develop if you have very prominent bony toes, thin skin, or any deformities of the toes or feet which cause the skin to rub more easily inside shoes. […] Tight or ill-fitting shoes are thought to be the main cause of most corns and calluses. […] Correcting poor footwear will reduce any rubbing or repeated friction on your skin. […] If you have had a corn or callus pared away, a recurrence will usually be prevented by wearing good footwear. […] A podiatrist can advise you about this.

#36 Corns and calluses: What’s the difference and how can I treat them?
https://www.medicalnewstoday.com/articles/172459
For calluses specifically, diabetes is also a risk factor. […] If the corn or callus is very painful, or if the person has diabetes, fragile skin, or circulatory problems, it is best to consult a doctor or a podiatrist who specializes in foot care. […] A person should never try to remove a corn or callus without medical supervision, especially if they also have diabetes or other underlying conditions. […] A doctor will usually recommend removal surgery only if the cause of the lesion is in the person’s bone structure, such as from a hammer toe or bunion or in some cases of a plantar callus. […] With treatment, corns and calluses may fade away, but without lifestyle or footwear changes, they may return.

#39 Corns – StatPearls – NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK470374/
Corns typically result from repeated accumulated mechanical trauma as well as other contributing factors like ill-fitting footwear, the presence of bony prominences (foot deformity), and certain physical activities. They are most common on the feet: on the dorsum of the toes, in the last interdigital web space, as well as on the soles of the feet. […] The incidence of corns on the feet has been reported to be ranging anywhere from 14% to 48%. Individuals with darkly pigmented skin are more prone to developing corns. They have been reported to affect older age groups with a slight female predominance due to wearing narrow shoes. The elderly are also subject to loss of the protective fat pad cushioning, called fat pad atrophy, which can increase the incidence of painful corn.

#41 A survey to investigate the association of pain, foot disability and quality of life with corns
https://pmc.ncbi.nlm.nih.gov/articles/PMC4673745/
Corns are a common foot problem affecting a large proportion of the population. […] Large epidemiological surveys also report a high prevalence of foot problems and pathologies: of 76,475 people attending a dermatology or general practice department, just over half (57 %) had a foot disease. […] Corns can be found in 14-48 % of people. […] A review of 392 participants attending an Australian podiatry clinic also reported that the most commonly presenting problems were nails, corns and calluses. […] In a survey to determine the current participant population managed by UK podiatrists, it was reported that the most frequently presenting problems were corns and callus (26 %) resulting in this being the most common type of treatment performed by the profession (19 %) in a typical working day.
