[Localization of solitary dermatophytic lesions in man].

The occurrence of three causative organisms of the so called intertriginous dermatophytoses--Epidermophyton floccosum, Trichophyton mentagrophytes var. interdigitale and T. rubrum--was compared according to the localization of the lesions. The differentiation of invasion into solitary and combined sites showed a prevalence of E. floccosum in solitary lesions and T. rubrum in combined lesions. In T. mentagrophytes var. interdigitale, the frequency of occurrence of both types of the lesions was approximately the same. The differences found suggest various adaptation-ability of dermatophytes to different parts of the body. The study of localization of solitary lesions is important from the epidemiological point of view because it assists in revealing the sources of dermatophytic infection and the ways of transmission.
