Dermatophytoses in Monterrey, México

Abstract

In the present report we reviewed a total of 2397 cases of dermatophytosis from superficial cutaneous lesions between the years 1978 and 1990. The cases included were from the Department of Dermatology at the University Hospital located in the city of Monterrey, México. A total of 726 tinea pedis, 613 tinea unguium, 441 tinea capitis, 395 tinea corporis and 222 tinea cruris cases were observed. The most commonly isolated dermatophyte species was Trichophyton rubrum (45%), followed by Trichophyton mentagrophytes (23.7%), Trichophyton tonsurans (21%), Microsporum canis (7.1%) and Epidermophyton floccosum (2.5%). Less frequently we isolated Microsporum audouinii, Microsporum gypseum, Trichophyton violaceum and Trichophyton verrucosum. Most of the cases were observed in the warmest months of the year (from March to September), and were equally distributed in both genders, except for tinea cruris which was more prevalent in men (3.5 : 1 ratio).
