Abstract
We report a case of tinea corporis caused by Trichophyton verrucosum which occurred in a patient residing in the Noto Peninsula. A 38-year-old male veterinarian developed an erythema on his left forearm. The KOH test and microscopic examination did not reveal fungus and so we diagnosed the erythema to be nummular eczema. However, a microscopic examination of a scale taken two weeks later, revealed hypha. We identified the fungus to be T. verrucosum based on its morphology and nutritional requirements. After diagnosing tinea corporis, we prescribed terbinafine hydrochloride cream. Ten days later, the terbinafine hydrochloride had caused a worsening of his erythema. Thereafter bifonazole cream cleared-up the problem within 5 weeks.
