RESUMO

INTRODUCTION: Onychomycosis, a nail fungus infection is the most frequent nail disease, constituting about half of all nail disorder. It can be caused by dermatophytes, yeasts and non- dermatophytes filamentous fungi. OBJECTIVE: Characterize the onychomycosis caused by filamentous fungi non- dermatophytes. (1) Verify after a clinical suspicion of onychomycosis, which are the frequency of fungi recovery, (2) examine, after a clinical suspicion of onychomycosis, which species of fungi are recovered, (3) Checking, among the total of identified species , which are the frequency of the species of filamentous fungi not dermatophytes. METHODS: Two hundred and five patients with clinical suspicion of onychomycosis were studied in the period from December 2003 to November 2004, through direct mycological examination and culture for fungus. RESULTS: The diagnosis of onychomycosis has been established by direct mycological examination, in 170 individuals. The etiological diagnosis was established by the culture for fungus. Among the 107 persons identified, the dermatophytes were recovered in 78.52% (N = 84), the yeast in 13.08% (N = 14) and filamentous fungi non- dermatophytes in 8,40% (N = 9). CONCLUSION: It is necessary to establish the etiological diagnosis of the cases of onychomycosis, as filamentous fungi non- dermatophytes occur often than ever considered and are its clinic features are indistinguishable from those of the dermatophytes.
