Trichophyton rubrum infections according to age, anatomical distribution and sex

Abstract

Trichophyton rubrum caused 72.9% of the cases of dermatophytosis observed in a sample of caucasoids from Philadelphia. Tinea pedis was found in 84% of the female and male patients with dermatophytosis. Tinea manuum occurred with equal frequency in both sexes whereas tinea unguium was more prevalent in females. Tinea cruris occurred almost exclusively in males. Infections of two or more anatomical sites were observed more frequently in males. The data are compared with those reported by Rosman (1966) from a similar study done in Copenhagen.
