Tinea cruris epidemiology (São Paulo, Brazil)

Abstract

In order to determine the epidemiology of tinea cruris in São Paulo, Brazil, an investigation was carried out from April 95 to March 1997. A total of 2000 individuals were studied, of whom 105 were suspected of having tinea cruris infection. Direct microscopy and/or culture were positive in 66 [62.8%] of the cases. Erythematous-scale plaques and erythematous-liquenificated plaques were the most frequently found clinical types. T. rubrum was the prevalent dermatophyte in 90% of the cases, followed by T. tonsurans (6%) and T. mentagrophytes (4%).
