Abstract

Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.
