Grzybica stóp
Diagnostyka i diagnoza

Grzybica stóp (tinea pedis) jest powszechną infekcją dermatologiczną, dotykającą 15-25% populacji, szczególnie w warunkach ciepłych i wilgotnych. Diagnostyka opiera się na badaniu klinicznym, obejmującym wywiad i ocenę zmian skórnych (zaczerwienienie, łuszczenie, pęknięcia, pęcherze w przestrzeniach międzypalcowych), jednak czułość i swoistość diagnozy klinicznej wynoszą odpowiednio 0,37 i 0,95 dla przestrzeni międzypalcowych oraz 0,47 i 0,94 dla podeszw. W diagnostyce laboratoryjnej najczęściej stosuje się test KOH, którego czułość waha się od 12% do 88%, zależnie od doświadczenia wykonującego i jakości zeskrobin. Hodowla grzybów, choć czasochłonna (2-3 tygodnie), pozwala na identyfikację gatunku i jest wskazana w przypadkach opornych lub nietypowych. Nowoczesne metody molekularne umożliwiają szybką (do 10 dni) i precyzyjną identyfikację patogenów, w tym infekcji mieszanych. Biopsja skóry i barwienie PAS są rzadziej stosowane, ale przydatne w diagnostyce różnicowej i potwierdzeniu infekcji paznokciowej.

Grzybica stóp – Diagnostyka

Grzybica stóp (łac. tinea pedis), powszechnie znana jako „stopa atlety”, jest jedną z najczęstszych infekcji grzybiczych skóry, szczególnie rozpowszechnioną w ciepłych, wilgotnych i miejskich środowiskach. Choroba ta dotyka około 15-25% populacji w dowolnym momencie i jest wysoce zaraźliwa1. Prawidłowa diagnostyka jest kluczowa dla skutecznego leczenia tej dolegliwości i odróżnienia jej od innych chorób skóry, które mogą przypominać grzybicę stóp2.

Badanie kliniczne

Diagnostyka grzybicy stóp często zaczyna się od badania klinicznego. Lekarz przeprowadza dokładny wywiad medyczny, zbierając informacje o objawach pacjenta (np. świąd, pieczenie), czynnikach ryzyka (korzystanie z publicznych obiektów sportowych, basenów, natrysków) oraz przeglądając historię medyczną w poszukiwaniu predysponujących czynników34. Następnie lekarz przeprowadza badanie fizykalne stóp, szukając charakterystycznych objawów takich jak zaczerwienienie, łuszczenie się skóry, pęknięcia, pęcherze, szczególnie w przestrzeniach międzypalcowych5.

W wielu przypadkach doświadczony lekarz może postawić diagnozę grzybicy stóp wyłącznie na podstawie jej charakterystycznego wyglądu6. Jednak czułość i swoistość klinicznej diagnozy nie jest idealna – w jednym z badań wynosiła odpowiednio 0,37 i 0,95 dla przestrzeni międzypalcowych oraz 0,47 i 0,94 dla obszarów podeszwowych7.

Warto podkreślić, że inne obszary ciała, takie jak paznokcie stóp, pachwiny czy dłonie, powinny być również zbadane pod kątem infekcji grzybiczej, co może wspierać diagnozę grzybicy stóp8.

Badania laboratoryjne

Aby potwierdzić diagnozę i wykluczyć inne schorzenia, często konieczne jest przeprowadzenie badań laboratoryjnych, szczególnie w przypadkach nietypowej prezentacji klinicznej, oporności na leczenie lub gdy infekcja manifestuje się jako hiperkeratotyczna, wrzodziejąca lub pęcherzowa9. Najczęściej wykorzystywane badania to:

Preparat bezpośredni KOH

Test z wodorotlenkiem potasu (KOH) jest najczęściej stosowanym badaniem laboratoryjnym w diagnostyce grzybicy stóp10. Procedura obejmuje:

  • Pobranie zeskrobin skóry z aktywnej krawędzi zmian za pomocą skalpela11
  • Umieszczenie materiału na szkiełku mikroskopowym
  • Dodanie roztworu wodorotlenku potasu (KOH), który rozpuszcza komórki skóry, pozostawiając nietknięte struktury grzybicze12
  • Obserwację pod mikroskopem, gdzie w przypadku infekcji dermatofitami widoczne są segmentowane strzępki grzyba13

14

Czułość badania KOH może się znacznie różnić w zależności od warunków i doświadczenia wykonującego, wahając się od 12% w badaniu przeprowadzonym wśród 27 flamandzkich lekarzy ogólnych do 88% w ośrodku opieki trzeciego stopnia w Nowej Szkocji15. Fałszywie ujemne wyniki preparatu KOH często wynikają z nieadekwatnych zeskrobin16.

Posiew grzybniczy

Hodowla grzybów może być wykonana w celu potwierdzenia diagnozy grzybicy stóp i identyfikacji gatunku patogenu17. Jest to szczególnie przydatne w przypadkach:

  • Utrzymującego się zaczerwienienia i świądu w określonym obszarze, co utrudnia diagnozę18
  • Konieczności określenia dokładnego typu patogenu19
  • Oporności na standardowe leczenie20

Hodowla grzybów wymaga pobrania materiału z zakażonego obszaru i umieszczenia go na specjalnym podłożu hodowlanym. Wyniki mogą być dostępne dopiero po 2-3 tygodniach, co jest znacznie dłuższym czasem oczekiwania niż w przypadku testu KOH21. W niektórych przypadkach hodowla może dać fałszywie ujemny wynik z powodu niewystarczającej ilości pobranego materiału22.

Analiza molekularna

Nowocześniejszą i szybszą metodą diagnostyczną jest analiza molekularna. Badanie to analizuje sekwencję DNA patogenów i dostarcza wyników w mniej niż 10 dni. Dodatkowo może identyfikować infekcje mieszane oraz patogeny, które nie rosną w hodowli23.

Biopsja skóry

Biopsja skóry rzadko jest wymagana do potwierdzenia diagnozy grzybicy stóp24. Może być jednak wykonana w celu wykluczenia:

  • Przewlekłej infekcji skóry innego pochodzenia25
  • Niezłośliwych guzów26
  • Nowotworów skóry27
  • Innych chorób skóry, które mogą naśladować grzybicę stóp28

W badaniu histopatologicznym biopsji skóry można zaobserwować neutrofile w warstwie rogowej, co powinno skłaniać do rozważenia infekcji dermatofitowej29.

Barwienie PAS

Najbardziej czułym, choć jednocześnie najdroższym testem diagnostycznym, jest barwienie kwasem nadjodowym i odczynnikiem Schiffa (PAS). Test można wykonać, umieszczając fragmenty paznokci lub zeskrobiny w 10% formalinie i przekazując je do laboratorium patologicznego30. W przypadku grzybicy stóp z zajęciem paznokci, test PAS może być szczególnie przydatny31.

Diagnostyka różnicowa

Grzybica stóp może być mylona z innymi chorobami skóry, dlatego ważne jest przeprowadzenie dokładnej diagnostyki różnicowej32. Do najczęstszych schorzeń, które mogą naśladować grzybicę stóp, należą:

  • Wyprysk kontaktowy – zapalenie skóry wywołane kontaktem z alergenem33
  • Łuszczyca – przewlekła choroba autoimmunologiczna charakteryzująca się łuszczącymi się blaszkami34
  • Atopowe zapalenie skóry – przewlekła, świądowa choroba zapalna skóry35
  • Erytrazma – bakteryjna infekcja skóry powodowana przez Corynebacterium minutissimum36

Badanie przy użyciu lampy Wooda (czarne światło) może być pomocne w rozpoznaniu erytrazmy, która wykazuje koralowo-czerwoną fluorescencję. Jednak w przypadku grzybicy stóp badanie to ma ograniczoną przydatność, ponieważ powszechne dermatofity powodujące tę chorobę nie fluoryzują w świetle ultrafioletowym37.

Kiedy należy zgłosić się do lekarza

Leczenie grzybicy stóp często rozpoczyna się od samodzielnego stosowania dostępnych bez recepty leków przeciwgrzybiczych38. Jednak istnieją sytuacje, w których konieczna jest konsultacja lekarska:

  • Wysypka na stopie nie poprawia się w ciągu dwóch tygodni od rozpoczęcia samoleczenia produktami przeciwgrzybiczymi dostępnymi bez recepty39
  • Pacjent choruje na cukrzycę i podejrzewa grzybicę stóp40
  • Występują oznaki infekcji: obrzęk zakażonego obszaru, ropa, gorączka41
  • Infekcja jest ciężka lub nawracająca42

Specjaliści zajmujący się diagnostyką grzybicy stóp

Kilka specjalności medycznych zajmuje się diagnostyką i leczeniem grzybicy stóp:

  • Lekarz podstawowej opieki zdrowotnej – może zdiagnozować i leczyć niepowikłane przypadki grzybicy stóp43
  • Dermatolog – specjalista w diagnozowaniu, leczeniu i zapobieganiu chorobom skóry, włączając grzybicę stóp44
  • Podolog – specjalista koncentrujący się na opiece nad stopami, w tym problemach dermatologicznych takich jak grzybica stóp45

Zarówno dermatolog, jak i podolog mogą przeprowadzić dodatkowe testy, takie jak posiewy skóry, aby potwierdzić diagnozę i dostosować leczenie do konkretnego przypadku46.

Nowoczesne metody diagnostyczne w grzybicy stóp

Współczesna diagnostyka grzybicy stóp wykracza poza tradycyjne metody mikroskopowe i hodowlane. Coraz częściej stosowane są zaawansowane techniki, które pozwalają na szybsze i dokładniejsze postawienie diagnozy47.

Testy immunochromatograficzne

Zestawy immunochromatograficzne zostały wprowadzone do diagnostyki powierzchownych infekcji grzybiczych, jednak okazały się mniej skuteczne w przypadku grzybicy stóp48. Te szybkie testy diagnostyczne opierają się na wykrywaniu specyficznych antygenów grzybiczych, ale ich czułość i swoistość w grzybicy stóp wymagają dalszych badań.

Diagnostyka telemedyczna

Wraz z rozwojem telemedycyny, pojawiły się możliwości wstępnej diagnostyki grzybicy stóp online. Certyfikowani pracownicy służby zdrowia mogą ocenić objawy pacjenta na podstawie wypełnionego kwestionariusza i zdjęć, a następnie postawić wstępną diagnozę i zaproponować plan leczenia. W przypadku konieczności przepisania leków, recepta może być wysłana bezpośrednio do wybranej przez pacjenta apteki49.

Sztuczna inteligencja w diagnostyce

Rozwój sztucznej inteligencji (AI) umożliwił stworzenie systemów wspomagających diagnostykę grzybicy stóp. Oprogramowanie AI, oparte na doświadczeniu lekarzy, może pomóc w wstępnej ocenie objawów i skierować pacjenta do odpowiedniego specjalisty50. Takie systemy mogą zadawać ukierunkowane pytania (np. „Czy paznokcie są grube, białe i mętne?”), aby lepiej określić prawdopodobieństwo wystąpienia grzybicy stóp51.

Znaczenie prawidłowej diagnostyki grzybicy stóp

Dokładna diagnostyka grzybicy stóp ma kluczowe znaczenie z kilku powodów:

Dobór właściwego leczenia

Prawidłowa diagnoza pozwala na wybór odpowiedniego leczenia przeciwgrzybiczego. W przypadku infekcji bakteryjnych, a nie grzybiczych, mogą być konieczne antybiotyki o szerokim spektrum działania, takie jak penicylina52. Leczenie grzybicy stóp może obejmować:

  • Leki przeciwgrzybicze miejscowe (kremy, maści, lotiony, pudry)53
  • Leki przeciwgrzybicze doustne w przypadku ciężkich lub opornych infekcji54

Wśród systemowych opcji leczenia grzybicy stóp wymienia się:

  • Terbinafina w dawce dobowej 250 mg przez 2 tygodnie55
  • Itrakonazol w dawce 200 mg dwa razy dziennie przez 1 tydzień56
  • Flukonazol w dawce 150 mg tygodniowo przez 2 do 6 tygodni57
  • Gryzeofulwina dla dorosłych w dawce dobowej 1000 mg formy mikrorozmiarowej przez 4 do 8 tygodni lub 750 mg formy ultramikrorozmiarowej przez 4 do 8 tygodni58

Należy zaznaczyć, że choć rzadko, mogą wystąpić działania niepożądane ze strony przewodu pokarmowego po przyjmowaniu flukonazolu59.

Zapobieganie powikłaniom

Nieleczona grzybica stóp może prowadzić do różnych powikłań, szczególnie u osób z grupy ryzyka, takich jak pacjenci z cukrzycą, obrzękiem, immunosupresją, hemiplegią i paraplegią60. Możliwe powikłania obejmują:

  • Wtórne zapalenie tkanki łącznej (cellulitis)61
  • Zapalenie naczyń chłonnych (lymphangitis)62
  • Ropne zapalenie skóry (pyoderma)63
  • Zapalenie kości i szpiku (osteomyelitis)64

U pacjentów z cukrzycą grzybica stóp może zwiększać ryzyko owrzodzeń stopy cukrzycowej i zakażeń stopy cukrzycowej65.

Zapobieganie rozprzestrzenianiu się infekcji

Infekcja może rozprzestrzeniać się na inne części ciała i na inne osoby66. Właściwa diagnoza i leczenie pomagają zapobiec przenoszeniu infekcji na inne obszary, takie jak pachwiny czy paznokcie stóp67.

Zapobieganie nawrotom

Dokładna diagnoza pozwala na zastosowanie odpowiednich środków zapobiegawczych, które zmniejszają ryzyko nawrotu grzybicy stóp68.

Algorytm diagnostyczny w grzybicy stóp

Na podstawie przeanalizowanych źródeł można zaproponować następujący algorytm diagnostyczny w przypadku podejrzenia grzybicy stóp6970:

  1. Badanie kliniczne – ocena objawów i wyglądu zmian skórnych na stopach
  2. Wywiad medyczny – zebranie informacji o czynnikach ryzyka, historii choroby i objawach
  3. Podstawowa diagnostyka laboratoryjna – wykonanie preparatu bezpośredniego KOH z zeskrobin skóry jako pierwszego testu potwierdzającego
  4. Dodatkowa diagnostyka – w przypadku wątpliwości lub nietypowego obrazu klinicznego:
    • Posiew grzybniczy dla identyfikacji patogenu
    • Biopsja skóry w przypadku podejrzenia innych schorzeń
    • Barwienie PAS dla zwiększenia czułości wykrywania
  5. Diagnostyka różnicowa – wykluczenie innych chorób mogących naśladować grzybicę stóp
  6. Konsultacja specjalistyczna – w przypadku ciężkiej infekcji, oporności na leczenie lub współistniejących chorób, takich jak cukrzyca

Zaproponowany algorytm może być modyfikowany w zależności od indywidualnych przypadków klinicznych, dostępnych metod diagnostycznych oraz doświadczenia lekarza71.

Właściwa diagnostyka grzybicy stóp stanowi fundament skutecznego leczenia, zapobiegania powikłaniom oraz minimalizacji ryzyka rozprzestrzeniania się infekcji i nawrotów choroby72.

    Around 15% to 25% of people are likely to have athlete’s foot at any one time. […] The infection can spread to other parts of the body and to other people. […] We conducted a systematic review and aimed to answer the following clinical question: What are the effects of topical treatments for athlete’s foot? […] We found 14 systematic reviews, RCTs, or observational studies that met our inclusion criteria. […] In this systematic review we present information relating to the effectiveness and safety of the following interventions: improved foot hygiene, including socks and hosiery; topical allylamines (naftifine and terbinafine); topical azoles (bifonazole, clotrimazole, econazole nitrate, miconazole nitrate, sulconazole nitrate, and tioconazole); and topical ciclopirox olamine. […] Topical allylamines (naftifine and terbinafine), topical azoles (clotrimazole, miconazole nitrate, tioconazole, sulconazole nitrate, bifonazole, and econazole nitrate) and topical ciclopirox olamine are all more likely to cure fungal skin infections compared with placebo.

    If you suspect you have athletes foot, the AllCare expert team of physicians can help diagnose your symptoms, as athletes foot can sometimes be mistaken for eczema, psoriasis, and other conditions that cause foot rashes. […] To identify the fungus causing your rash, we may perform a skin sample test, where a small portion is scraped and examined under a microscope, with results usually available the next day. A skin culture can also be grown in a lab to determine the exact strain, though it takes up to three weeks. Alternatively, a skin biopsy may be done to rule out other skin diseases or cancers that could mimic athletes foot. […] While some over-the-counter medicines may relieve your athletes foot symptoms, its always a good practice to see your doctor to ensure you actually have athletes foot and not another skin condition that may mimic the same symptoms. […] If over-the-counter treatments are ineffective or if the infection is severe, consult a healthcare provider for further evaluation and treatment.

    When visiting a doctor, the basic diagnosis procedure applies. This includes checking the patient’s medical history and medical record for risk factors, a medical interview during which the doctor asks questions (such as about itching and scratching), and a physical examination. Athlete’s foot can usually be diagnosed by visual inspection of the skin and by identifying less obvious symptoms such as itching of the affected area. […] If the diagnosis is uncertain, direct microscopy of a potassium hydroxide preparation of a skin scraping (known as a KOH test) can confirm the diagnosis of athlete’s foot and help rule out other possible causes, such as candidiasis, pitted keratolysis, erythrasma, contact dermatitis, eczema, or psoriasis. Dermatophytes known to cause athlete’s foot will demonstrate multiple septate branching hyphae on microscopy. […] A Wood’s lamp (black light), although useful in diagnosing fungal infections of the scalp (tinea capitis), is not usually helpful in diagnosing athlete’s foot, since the common dermatophytes that cause this disease do not fluoresce under ultraviolet light.

    A physical examination and laboratory tests are common avenues for diagnosing foot fungus. […] A healthcare practitioner will examine the affected area, usually the feet, to look for signs and symptoms of Athlete’s Foot. They will check for redness, scaling, cracking, blistering, and other characteristic skin changes associated with the infection. […] Your doctor may perform a skin scraping test. They will carefully scrape off a small sample of the skin involved and examine it under a microscope. The sample gets treated with a potassium hydroxide (KOH) solution, which helps to dissolve the skin cells and reveal any fungal elements. This test can confirm the fungus responsible for Athlete’s Foot. […] In certain situations, a culture test may identify the specific type of fungus causing the infection. A sample of the affected skin is collected and placed in a culture medium that promotes the growth of fungi. This test allows the healthcare professional to identify the fungus and specify the most appropriate course of action.

  • #7 Tinea Pedis Clinical Presentation: History, Physical Examination, Complications
    https://emedicine.medscape.com/article/1091684-clinical
    Commonly, tinea pedis (athlete’s foot) patients describe pruritic, scaly soles and, often, painful fissures between the toes. Less often, patients describe vesicular or ulcerative lesions. Some tinea pedis patients, especially elderly persons, may simply attribute their scaling feet to dry skin. […] In one study, the sensitivity and specificity for clinical diagnosis were 0.37 and 0.95, respectively, for tinea pedis in the interdigital areas and were 0.47 and 0.94, respectively, for tinea pedis in the plantar areas. […] Secondary cellulitis, lymphangitis, pyoderma, and even osteomyelitis can result from mycotic infections of the feet, including tinea pedis. These complications are seen more frequently in patients with conditions such as chronic edema, immunosuppression, hemiplegia and paraplegia, and diabetes. In diabetic patients, tinea pedis may increase the risk of diabetic foot ulcers and diabetic foot infections.
  • #8 Tinea pedis (fungal foot infection)
    https://dermnetnz.org/topics/tinea-pedis
    Tinea pedis is a foot infection due to a dermatophyte fungus. It is the most common dermatophyte infection and is particularly prevalent in hot, tropical, urban environments. […] Interdigital involvement is most commonly seen (this presentation is also known as athletes foot, although some people use the term for any kind of tinea pedis). […] The diagnosis of tinea pedis can be made clinically in most cases, based on the characteristic clinical features. Other typical sites, such as toenails, groin, and palms of the hands, should be examined for fungal infection, which may support a diagnosis of tinea pedis. […] Diagnosis is confirmed by skin scrapings, which are sent for microscopy in potassium hydroxide (when segmented hyphae may be observed) and culture (mycology). Culture may not be necessary if typical fungal elements are observed on microscopy.

    Athlete’s foot is caused by a fungal infection of the skin on the foot. The diagnosis of tenia pedis is generally made based upon the clinical presentation. A definitive diagnosis is made by taking a scraping of the skin and culturing it. It may take up to three weeks for the culture to grow the fungus. In some instances the culture may present a false negative result because the skin scraping was inadequate. Some doctors may perform a KOH prep of a skin scraping. This is examined under a microscope and may reveal elements that can make the diagnosis. […] The chronic form of athletes foot is a relatively noninflamatory type of infection. It is characterized by a dull redness to the skin and pronounced scaling.

A definitive diagnosis is made by taking a scraping of the skin and culturing it. It may take up to three weeks for the culture to grow the fungus. In some instances the culture may present a false negative result because the skin scraping was inadequate. Some doctors may perform a KOH prep of a skin scraping. This is examined under a microscope and may reveal elements that can make the diagnosis. […] The chronic form of athletes foot is a relatively noninflamatory type of infection. It is characterized by a dull redness to the skin and pronounced scaling.

    Athletes foot may seem trivial, but it is important to get a diagnosis in order to rule out other possible infections, as there are many other foot diseases. With an accurate diagnosis, affected individuals can obtain the appropriate treatment quickly, avoid complications and take the necessary steps to avoid contaminating others. […] During the consultation, the doctor examines the foot and looks for the characteristic signs of athletes foot. He or she may also examine the groin, hands and nails for signs of fungal infection in these areas. […] If necessary, skin samples can be taken via a quick, painless skin scraping procedure to confirm the presence and type of fungi. While a variety of diagnostic tools are available (e.g., microscopy, histology, dermoscopy, etc.), laboratory testing methods are also employed, such as fungal cultures and molecular analysis. […] Molecular analysis is a much faster method. It analyzes the pathogens DNA sequence and produces results in less than 10 days. In addition, it can be used to identify mixed infections and agents that do not grow in a culture.

    In suspected tinea pedis (athlete’s foot), direct potassium hydroxide (KOH) staining for fungal elements should be ordered. Usually, the fungal elements are easily identified from scaly lesions. […] A fungal culture may be performed to confirm the diagnosis of tinea pedis and to identify the pathogenic species. […] Immunochromatography kits have been introduced for the diagnosis of superficial fungal infections, but they have proved less effective in the setting of tinea pedis. […] A skin biopsy and histopathological study are rarely needed to confirm a diagnosis of tinea pedis. […] Neutrophils may be noted within the stratum corneum, a finding that should prompt consideration of a dermatophyte infection.

[…] Secondary cellulitis, lymphangitis, pyoderma, and even osteomyelitis can result from mycotic infections of the feet, including tinea pedis. These complications are seen more frequently in patients with conditions such as chronic edema, immunosuppression, hemiplegia and paraplegia, and diabetes. In diabetic patients, tinea pedis may increase the risk of diabetic foot ulcers and diabetic foot infections.

    Around 15% to 25% of people are likely to have athlete’s foot at any one time. […] The infection can spread to other parts of the body and to other people. […] We conducted a systematic review and aimed to answer the following clinical question: What are the effects of topical treatments for athlete’s foot? […] We found 14 systematic reviews, RCTs, or observational studies that met our inclusion criteria. […] In this systematic review we present information relating to the effectiveness and safety of the following interventions: improved foot hygiene, including socks and hosiery; topical allylamines (naftifine and terbinafine); topical azoles (bifonazole, clotrimazole, econazole nitrate, miconazole nitrate, sulconazole nitrate, and tioconazole); and topical ciclopirox olamine. […] Topical allylamines (naftifine and terbinafine), topical azoles (clotrimazole, miconazole nitrate, tioconazole, sulconazole nitrate, bifonazole, and econazole nitrate) and topical ciclopirox olamine are all more likely to cure fungal skin infections compared with placebo.
  • #67 Athlete’s Foot: Treatment at Home & When to See a Doctor
    https://resources.healthgrades.com/right-care/skin-hair-and-nails/when-to-see-a-doctor-for-athletes-foot
    If you’ve tried home treatments for athlete’s foot without success, see a doctor. […] Because the condition can be spread to other parts of your body and to other people, it’s important to see a doctor if you’ve tried athlete’s foot treatments at home without success. […] You can expect to see some improvement after one week of treatment with an antifungal cream or other medication, and the infection should be nearly gone after two weeks of treatment at home, although sometimes it may take longer. If you haven’t seen any improvement or the infection appears to be getting worse, call your doctor. […] It’s important to seek treatment before the infection spreads to the rest of your foot or other parts of your body, such as your groin or toenails. […] A primary care physician or dermatologist can diagnose athlete’s foot and recommend the best treatment. To rule out other medical conditions, such as eczema, your doctor might want to scrape your foot to confirm you have fungus spores on your skin. After confirming you have athlete’s foot, your doctor may prescribe a stronger medication, usually a cream or, in severe cases, a pill. […] Don’t dismiss athlete’s foot symptoms. Because the condition spreads easily, it’s important to catch it early and start treatment right away. If you notice the symptoms and home treatment isn’t working, consult with your doctor.

    Tinea pedis, also known as athlete’s foot, results from dermatophytes infecting the skin of the feet. […] A practice gap exists among clinicians in recognizing the risk factors and potential complications associated with tinea pedis. […] Bridging this gap is crucial to ensure timely diagnosis, effective management, and the prevention of complications in patients with this fungal skin infection. […] Confirmation through microscopy and culture may be necessary. […] Microscopic examination of scrapings from the affected site can confirm the diagnosis by demonstrating segmented hyphae. […] Although the physical examination may strongly indicate a dermatophyte infection, tinea can overlap with other skin conditions. […] Patients who do not respond to topical treatment require systemic therapy.

    https://www.aafp.org/pubs/afp/issues/2014/1115/p702.html
    Tinea infections can be difficult to diagnose and treat. […] The diagnosis of onychomycosis should generally be confirmed with a test such as potassium hydroxide preparation, culture, or periodic acid-Schiff stain before initiating treatment. […] Tinea corporis, tinea cruris, and tinea pedis can often be diagnosed based on appearance, but a potassium hydroxide preparation or culture should be performed when the appearance is atypical. […] The diagnosis of onychomycosis should usually be confirmed with a KOH preparation, culture, or PAS stain because the treatment is long and potentially expensive, and the nonfungal mimics are common. […] The most sensitive diagnostic test, and the most expensive, is the PAS stain, which can be performed by placing toenail clippings or curettings in 10% formalin and transporting them to the pathology laboratory.
