Most people do not have clinical disease. Differential Diagnosis A variety of diagnostic techniques are available with which to identify superficial fungal infection. Plantar pustules may be seen without the typical plaques of psoriasis. Pitting of the nails may be a clue to the diagnosis. The KOH exam and fungal culture are often negative.
Topical therapies are usually effective for tinea pedis.
Topical agents available include imidazole preparations, allylamines, and adjunctive agents. Topical creams are typically applied twice daily to the affected areas. Systemic therapy is rarely required for tinea pedis, except in rare disabling cases. Treatment of dermatophytes should include maintenance of a dry environment, as the infection thrives with moisture. Cotton wisps may be placed between the toes to further increase aeration.
