Abstract

Tinea cruris is a subacute or chronic dermatophytosis. This report describes a 30-year-old man presenting with a history of bullous erythematous along with itching of his crural regions. On the basis of clinical findings, the lesions were diagnosed as contact dermatitis and pustular psoriasis, so he was treated by local and systemic corticosteroids but pustular lesions were progressed on the affected sites. By using mycological and histological examinations, dermatophytosis caused by Trichophyton mentagrophytes var. mentagrophytes was confirmed. The patient was successfully treated with itraconazole and local antifungal treatments.
