Dermatophytes produce an infection commonly known as ringworm or tinea. Isolates of the Afro-Asiatic subpopulation most commonly manifest clinically as tinea corporis and tinea capitis. In children, nummular dermatitis is commonly confused with tinea corporis. This is the same treatment plan for tinea or pityriasis versicolor. Tinea corporis is caused by a tiny fungus known as dermatophyte. Infection usually occurs as tinea capitis with suppuration and kerion formation. "Microsporum canis" is among the most common dermatophytes associated with tinea capitis and tinea corporis. Individuals with tinea pedis are likely to have infection at multiple sites. However the most common cause in humans seems to be tinea capitis and tinea corporis. Tinea, or ringworm, is any of a variety of skin mycoses. Contrary to the name, tinea pedis does not solely affect athletes. Moderate cases of tinea barbae can be treated with topical antifungal medications. Examples of dermatomycoses are tinea and cutaneous candidiasis. It is typically more aggressive than tinea pedis but similar in look.
