Objective To determine the pattern of infectious agents causing tinea capitis (TC) in adult patients in adult patients in Tunisia. Methods From January 1990 to December 2005, we retrospectively collected all cases of adult TC, confirmed by the mycological examination. Results Sixty patients (18 male, 42 female) with a mean age of 34.5 years were diagnosed as having adult TC among a total number of 1137 cases of TC (5.27%). Clinical features were polymorphic and diagnosis was made on mycological examination. Culture identified Trichophyton violaceum in 36 cases (60%), Microsporum canis in 12 cases (20%), Trichophyton schoenleini in 7 cases (12%), Trichophyton verrucosum in two cases (3.5%), and Trichophyton mentagrophytes and Trichophyton rubrum in one case (each 1.77%). Culture was negative in one case. Treatment consisted of administration of Griseofulvin at the dose of 20–25 mg/kg/d during 6–8 weeks associated with antifungal topics. A complete recovery was noted in 55 cases and relapse occurred in two patients. A scary alopecia was observed in one patient and two patients were lost to follow-up. Conclusion Trichophyton violaceum remains the most common etiological agent of adult TC in Tunisia. Microsporum canis is rising rapidly most notably due to the high frequency of asymptomatic carriage by domestic animals. [ABSTRACT FROM AUTHOR]
