Tinea pedis observed in Cagliari, Italy, between 1996 and 2000.

摘要

The aim of this study was to verify the incidence of tinea pedis in patients observed in the Department of Dermatology of the University of Cagliari, Italy, in the period from 1996 to 2000. We examined 722 patients, 536 with lesions and 186 without lesions of the feet and in 169 of them (23.4%) we diagnosed tinea pedis. All patients suffering from tinea pedis belonged to the group with lesions. In the 536 patients with clinical manifestations which were evident to a certain degree, microscope and cultural examination gave positive results for dermatophytes in 169 cases (31.5%). The most frequently isolated dermatophyte was Trichophyton mentagrophytes (51.5%), followed by Trichophyton rubrum (45.2%) and Epidermophyton floccosum (3.3%). In the 186 patients without lesions, direct microscope examination was consistently negative while cultural examination showed the growth of sparse colonies of Candida albicans in two cases (1.1%) We analysed distribution by sex, age, residence, occupation and clinical manifestations. Stressing the high frequency of tinea pedis in this region, the discovery of a dermatophytic infection of the feet with an absence of signs and symptoms is an exceptional event.
