Dermatophytosis is the most common mycosis in the world up to 80% caused by Trichophyton rubrum. The aim of the present study was to describe the clinical characteristics of the dermatophytosis caused by T. rubrum in a dermatological outpatient clinic during a ten years period, from 1996 to 2005. We collected the data from patients with a dermatophytosis from which we have isolated T. rubrum. A total of 776 patients with dermatophytosis caused by T. rubrum were found. A slight predominance of female patients (56.2%) was observed. The most commonly affected age group was those in the third to the fifth decade of life, and house working women (33.5%) were predominant. Onychomycosis was found in 63% of the cases, tinea pedis in 22.7%, tinea corporis in 5.2% and tinea cruris in 2.8%. In onychomycosis, the first toe nail was the most commonly affected (58.9%) and the dystrophic type was seen in 50.7% of them.
