A patient with cutaneous and reticulo-endothelial lesions, lymphadenopathy and osteitis caused by Trichophyton violaceum is presented. Two types of skin lesions were found: 1. Erythematous, scaly plaques on the arms, chest and abdomen; 2. areas of diffuse infiltration, granulomatous ulceration, fistulation and destruction of the sternal bone. Long-term treatment with penicillin, streptomycin, sulfonamides, and griseofulvin, gave temporary improvement.
