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.
表现为结节病样斑块的副球孢子菌病可能会被误诊为麻风，尤其是在涉及共同流行地区时。我们报告了一例巴西男性患者，其左耳及邻近区域出现溃疡性斑块。该斑块在临床和组织病理学上均模拟了1型结核样麻风反应。常规和Fite-Faraco染色未检测到病原体的神经周围肉芽肿强化了该诊断。仅在从溃疡区域进行第二次活检后才确诊为副球孢子菌病。
