Successful treatment with fluconazole of tinea corporis caused by Trichophyton verrucosum (barn ich).

A student in a veterinary program noted an inflammatory tinea corporis on the right forearm after working with cows. Culture grew Trichophyton verrucosum. A nine-day course of treatment with oral fluconazole, 100 mg daily, resulted in prompt resolution. Awareness of the clinical presentations of barn itch, and familiarity with wet mount and histopathologic features, and special growth requirements of T. verrucosum will facilitate prompt diagnosis and treatment. Therapy with newer antifungal agents such as fluconazole may offer advantages over grisefulvin.
