[Dermatomycosis due to Trichophyton verrucosum in Sfax-Tunisia].
Trichophyton verrucosum is a zoophilic dermatophyte. It can be responsible of various clinical aspects especially inflammatory lesions of skin and scalp. The aim of this study was to determine the clinical and epidemiological characteristics of dermatophytosis due to T. verrucosum.


METHODS
It is a retrospective study realized on 35,918 patients suspected to have superficial mycoses in a 13-year-period (from 1998 to 2010).


RESULTS
T. verrucosum was isolated in 178 patients corresponding to 1.2% of all dermatophytosis. Ochraceum variety was the most frequent (60%), followed by album variety (40%). Frequency of isolated T. verrucosum increased passing from one case in 1998 to 37 cases in 2010. The mean age was 22.7 years (range: 1.5-71 years). A percentage of 74.2 of our patients were male and 61% were from urban regions. A percentage of 32.5 could link their clinical lesions to contact with an animal (mainly cattle and sheep). Other family members were infected by tinea in 7.3% of cases. Tinea corporis was the most frequent (62.2%), followed by tinea capitis (31.6%). Ten cases of sycosis, one case of tinea pedis and one case of pubic tinea were diagnosed. Lesions of skin were erythemato-squamous (82.5%) and pustulo-inflammatory (17.5%), affecting mainly upper limb (58.3%) and face (25.8%). For tinea capitis, lesions were squamous (30.8%) and pustulo-inflammatory (41%). Eleven cases of kerion celsi were diagnosed (28.2%). Patients were affected in one site (79.7%), two sites (16.9%) and three or more (3.4%).


CONCLUSIONS
Dermatophytosis due to T. verrucosum is in recrudescence in our region. This finding may be explained by changing behaviors and activities of the population with a low socioeconomic level who kept a larger number of domestic animals at homes.
