Sarcoid-like paracoccidioidomycosis presenting with perineural granuloma.
Paracoccidioidomycosis presenting as a sarcoid-like plaque may be misdiagnosed as leprosy, especially when shared endemic areas are concerned. We report the case of a Brazilian male patient presenting with an ulcerated plaque on his left ear and neighboring areas. The plaque simulated tuberculoid leprosy type 1 reaction, both clinically and histopathologically. A perineural granuloma with no organisms detected by routine and Fite-Faraco staining reinforced that diagnosis. Paracoccidioidomycosis was confirmed only after a second biopsy, taken from the ulcerated area.
