“…Studies conducted in European countries, United States of America, Mexico and Argentina, also confirm the higher percentage of isolation of T. rubrum 10,15,23,34,35 . This is an anthropophilic fungus perfectly adapted to human keratinized tissues causing a mild chronic inflammation and rarely infects animals 49 .…”

SUMMARYDermatophytosis are superficial mycoses caused by fungi that can invade stratum corneum and keratinized tissues. In order to study the frequency of dermatophytes species and the clinical manifestations caused by these fungi, in São Paulo, SP, Brazil, the authors analyzed cultures isolated at the Mycology Laboratory from a selected population (15,300 out-patients of the Hospital das Clínicas, Department of Dermatology, Faculty of Medicine of University of São Paulo) from January 1992 to June 2002.The most prevalent dermatophyte was Trichophyton rubrum (48.7%), followed by Microsporum canis (20.9%), Trichophyton tonsurans (13.8%), Trichophyton mentagrophytes (9.7%), Epidermophyton floccosum (4.1%), and Microsporum gypseum (2.5%). These agents determined more than one clinical manifestation, i.e., tinea corporis (31.5%), tinea capitis (27.5%), tinea unguium (14.8%), tinea cruris (13.9%), tinea pedis (9.9%), and tinea manuum (1.9%). Clinical variants of dermatophytosis and their relationship to the etiologic agents were studied and the results were compared to those obtained in previous studies in other regions of Brazil and in other countries.

“…Sporadic cases of infection due to M. gypseum (mainly tinea corporis and capitis) have been described in North (3,4), Central (5,6) and South America (7,8), Africa (9), and Europe (2,(10)(11)(12). An epidemic of onychomycosis, a disease rarely caused by M. gypseum (13), was reported in Czechoslovakia in greenhouse workers who had continuous contact with heavily contaminated soils (14). Most infections due to M. gypseum reported in the literature have been in adults (15)(16)(17).…”

Tinea incognito is a dermatophytosis of atypical clinical character due to the absence of classic features of ringworm. It is caused by prolonged use of topical steroids, sometimes prescribed as a result of incorrect diagnosis. The cases reported in the literature have different clinical presentations and have generally been in adults. We report three children with tinea incognito in whom the lesions were psoriasis-like, eczema-like, and lichenoid, respectively. Diagnosis was confirmed by mycologic examination, which led to the identification of Microsporum gypseum, a geophilic dermatophyte which is an infrequent agent of mycotic infection in humans.

In the former Czechoslovakia, 9 an onycomycosis epidemic was reported, in workers who stayed in greenhouses and had direct contact with highly contaminated soil. In another report from Brazil, seven persons from a day care center were infected and the source of contamination was a sandpit used for entertainment, highly colonized by the fungus.…”

Infections caused by dermathophytes in the scrotal skin are uncommon especially due to Microsporum gypseum, which may form scutular or favus-like lesions. We report two patients with this type of tinea: one immune suppressed by HIV infection and another immunocompetent without comorbidity. In the literature we found only two reports in immunocompetent patients and some in immune suppressed with similar symptoms.
