Its medical name is tinea pedis, a member of the group of diseases or conditions known as tinea, most of which are dermatophytoses (fungal infections of the skin), which in turn are mycoses (broad category of fungal infections). Globally, athlete's foot affects about 15% of the population. [4]
Athlete's foot, known medically as tinea pedis, is a common skin infection of the feet caused by a fungus. [2] Signs and symptoms often include itching, scaling, cracking and redness. [3] In rare cases the skin may blister. [6] Athlete's foot fungus may infect any part of the foot, but most often grows between the toes. [3]
Trichophyton rubrum is one of the most common causes of chronic tinea pedis commonly known as athlete's foot. [12] Chronic infections of tinea pedis result in moccasin foot, in which the entire foot forms white scaly patches and infections usually affect both feet. [10] Individuals with tinea pedis are likely to have infection at multiple sites ...
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [ 1 ]
Tinea capitis is characterized by irregular or well-demarcated alopecia (balding) and scaling. Infected hair shafts are broken off just at the base, leaving a black dot just under the surface of the skin, and alopecia can result. [3] Scraping these residual black dot will yield the best diagnostic scrapings for microscopic exam.
Epidermophyton floccosum is a filamentous fungus that causes skin and nail infections in humans. [1] This anthropophilic dermatophyte can lead to diseases such as tinea pedis (athlete's foot), tinea cruris, tinea corporis and onychomycosis.
[3] [6] Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. [7] Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin.
Tinea cruris is often associated with athlete's foot and fungal nail infections. [4] [5] Rubbing from clothing, excessive sweating, diabetes and obesity are risk factors. [6] [8] It is contagious and can be transmitted person-to-person by skin-to-skin contact or by contact with contaminated sports clothing and sharing towels. [3] [5]
