Dermatophytosis in outpatients attending the Marchoux Institute in Bamako

Objective. To describe features of dermatophytosis in outpatients attending the Marchoux institute in Bamako, Mall. Patients and methods. We conducted a one year study of dermatophytosis prev alence and etiology in outpatients attending the Marchoux Institute in Bama ko, Mall, West Africa. Results. Among 384 patients, 205 (53.4%) had dermatophytosis. Sex and occup ation had no influence on the development of dermatophytosis. However, derm atophytosis was more frequently observed in patients under the age of 30 ye ars (p < 0.001). The causal agents were Trichophyton soudanense (45.37%,) T richophyton rubrum (35.12%) Microsporum langeronii (17.56%), and Trichophyt on violaceum (1.95%). The main localizations were the scalp (38.54%), glabr ous skin (35.12%) and skin folds (21%). Tinea corporis (40.0%), tinea capit is (38.54%), and tinea unguium (21.0%) were the main clinical manifestation s. Tinea unguium and tinea corporis predominated among men (p = 0.02) and w omen(p = 0.01) respectively. Tinea capitis and tinea corporis were mainly d ue to T. soudanense. The second most frequent causal fungus was M. langeron ii for tinea capitis and T. rubrum for tinea corporis. Tinea unguium was du e only to T. rubrum and there was one case of onyxis due to T. violaceum.
