Report of a Case.—  In March 1976, a 53-year-old farmer was referred to our clinic for treatment of a skin eruption on the right forearm (Fig 1). Other clinical findings were normal. Histologically, a specimen of the lesion showed dark-brown, thick-walled spores of the fungus among marked granulomatous changes. A colony of Fonsecaea pedrosoi (Fig 2) grew from a culture of the tissue fragment on Sabouraud's glucose agar.We tentatively started continuous local heat therapy with a pocket warmer that was bandaged directly to the patient's arm at the lesion.

Comment.—  Conti-Diaz1 has confirmed
