This paper reports an unusual case of paracoccidioidomycosis with ulcerations in the head and nose in a Brazilian man. For diagnosis, direct microscopic examination of ulcer secretion and skin samples treated with potassium hydroxide was performed. The isolation of Paracoccidioides brasiliensis occurred at 28ºC and 37ºC on Sabouraud agar with chloranphenicol. Diagnosis was established by the presence of isolated and multiple budding yeast-like cells and typical fungus growth of P. brasiliensis.
