Pubogenital tinea or tinea genitalis represents a rare type of dermatophytosis which, however, is increasingly being diagnosed. The mons pubis is affected, but also the outer regions to the penis shaft and the labia together with the groins. Pubogenital tinea is a more superficial erythrosquamous type, but strong inflammatory dermatomycoses of the genital area as tinea genitalis profunda ranging to kerion celsi are observed. A total of 30 patients (14-63 years of age, 11 men and 19 women) with pubogenital tinea are described. Most patients originated from Graz, Austria, while 2 patients were from Germany (Saxony and Isle of Sylt). Causative agents were mainly zoophilic dermatophytes: Microsporum (M.) canis (11), Trichophyton (T.) interdigitale (9), T. anamorph of Arthroderma benhamiae (2), and T. verrucosum (1). Anthropophilic fungi were T. rubrum (6) and T. tonsurans (1). Anamnestic questions should include contact with pets, physical activities, and travel. Genital shaving and concurrent tinea pedis and onychomycosis are disposing factors. Treatment consisted of oral antifungals except in the three women who were pregnant. Preferably, itraconazole or terbinafine was used, while in a single case, fluconazole was administered. Griseofulvin was not used, because this classic systemic antifungal agent is not allowed any more in Austria. In one patient, oral antifungal therapy was changed from itraconazole to terbinafine due to inefficacy.
