[Five cases of chromomycosis in Gabon (author's transl)].

Five cases of chromomycosis were studied in the parasitological and mycological department of the National Laboratory and C.U.S.S. in Libreville (Gabon). Different types of lesions were observed which were more often maculous than verrucous. In one case, it was localized on the upper limb, and in four cases on the lower limbs. They all were diagnosed after a 2 to 25 years evolution. Fonsecaea pedrosoï was isolated in every case. Direct examinations always recovered the classical scleratic cells : in one case it was budding, and in two cases abundant mycelium was seen. No epidemiological argument can explain the geographical distribution.
