Abstract

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.Paracoccidioidomicose expressando-se como placa sarcoídica pode ser confundida com hanseníase, especialmente em zonas endêmicas comuns às duas condições. Apresentamos um paciente brasileiro, com placa ulcerada na orelha direita e em áreas vizinhas que simulava, clinica e histopatologicamente, hanseníase tuberculoide em reação tipo 1. O encontro de granuloma perineural, sem parasitas detectáveis às colorações de rotina e Fite-Faraco, reforçou a hipótese de hanseníase. Apenas com uma nova biópsia, desta vez da área ulcerada, a paracoccidioidomicose pôde ser confirmada.
