Infections caused by dematiaceous fungi and their anatomoclinical correlations.

The Exophiala genus comprises dimorphic melanized fungi responsible for a spectrum of diseases including phaeohyphomycosis, mycetoma, chromoblastomycosis and fungemia. The E. jeanselmei species is predominant in such infections, followed by E. dermatitidis. This paper aims at reporting four cases and at discussing clinical, histologycal, mycologycal and epidemiologycal aspects for its diagnosis.
