A critical survey of 1000 cases of dermatophytosis in the tel aviv area during 1970–1975

Abstract

Clinical and mycological data on 1000 cases of dermatophytosis seen from 1970 to 1975 are reported. Tinea pedis was present in 44%, T. rubrum being the main causative agent; nail involvement was present in 41% of these cases. Tineainguinalis was present in 13%, 38% of them females, withT. rubrum isolated in 87% and the swimming-pool incriminated as the main source of contamination. There were various manifestations of tinea corporis in 128 patients, withT. rubrum responsible in 91%. Among the 21 cases of tinea capitis, there was one adult female with a kerion-type due toT. violaceum, 4 cases due toM. gypseum and 2 toM. canis. Tinea favosa was seen in 6 patients, all of them females and one with a spreading fungus on the soles and palms. Amonh the 10 cases with tinea barbae,T. rubrum was found in 4,T. tonsurans in 3,T. mentagrophytes in 2 andM. gypseum in one. There were widespread lesions ofT. rubrum located on large areas of the body and including the legs, arms, groins and nails, in 11 patients with other disorders, including diabetes, Cushing's syndrome and lymphoma.

It was apparent that the dermatophytic flora of Israel comprises 10 dermatophytes,T. rubrum being the predominant agent of infection (in more than 80%), with a gradually increasing incidence evident. The other agents found in our survey wereT. mentagrophytes, T. violaceum, T. schoenleinii, T. tonsurans (found sporadically),E. floccosum andMicrosporum spp.M. canis andM. gypseum, the latter being reported for the first time in this country.T. verruccosum andT. megnini, mentioned in former publications, were not found in this survey.
