Tinea cruris is a dermatophytosis that mainly affects males. Infections in females are rare, and there are no known data on the frequency of tinea cruris in female prostitutes. We describe seven female prostitutes with tinea cruris with on age range of between 19-34 years (mean 25.3). Each prostitute had a mean of 50 sexual partners per month. Four Trichophyton mentagrophytes (57.1%), 2 T rubrum (28.6%), and 1 Epidermophyton floccosum (14.3%) isolates were cultered. Tinea cruris transmission is mainly indirect, but direct contact may serve to transmit the disease in some cases, and the spread of active lesions in prostitutes through multiple contacts among with their clients is possible.
