Incidence of dermatophytosis in Huelva (south and southwest areas) was investigated during a period of seven years (1989-95). The relevant data included age, sex, clinical form of the tinea and dermatophyte identified. We report 105 patients with 120 positive dermatophyte cultures. Microsporum cants (39,2%), Tricophyton rubrum (25,8%) and Tricophyton mentagrophytes -var. mentagrophytes- (13,3%) ... [Show full abstract] were the predominantly isolated dermatophytes. The most frequent clinical type was tinea capitis (38,3%) followed by tinea carports (35,8%). We compared our results with others from various Spanish provinces.
