Trichophyton rubrum Tinea Capitis in a Young Child

While the primary etiologic agent of tinea capitis in the United States has varied over the past century, the last several decades have been marked by a predominance of infection with Trichophyton tonsurans. Related anthropophilic organisms commonly isolated in other dermatophytoses are infrequently observed in tinea capitis. We report the unusual occurrence of tinea capitis in a young boy infected with Trichophyton rubrum.
