Tinea Pedis (Athlete's Foot)
Key Points
Tinea pedis is the most common dermatophytosis because moisture resulting from foot sweating facilitates fungal growth. Consider the diagnosis if patients have lesions of the toes and/or feet that are intertriginous, ulcerative, hyperkeratotic, or vesicobullous. Also consider hand and feet dermatitis (dyshidrotic dermatitis), palmoplantar psoriasis, and allergic contact dermatitis. Treat using topical and occasionally oral antifungals as well as drying measures and agents.
