Chromoblastomycosis: clinical and mycologic experience of 51 cases.

This is a study of 51 cases of chromoblastomycosis detected in a 17-year period, all of which were clinically and mycologically proven by direct examinations, cultures and biopsies. The therapeutic results of the various treatments used are reported. Most cases were males (36 of 51; 70%), the mean age was 35 years and farmers predominated (74%); the most frequent lesions were in the lower limbs (54%). Major clinical presentations were nodular (41%) and verrucous (26%). The principal aetiologic agent isolated was Fonsecaea pedrosoi (90%). Overall results of the various treatments were as follows: 31% were cured, 57% improved and 12% failed. The best results were obtained with cryosurgery for small lesions, with itraconazole for large ones, and in some cases the combination of both treatments.
