Lepromatous leprosy can present with skin nodules which can be misdiagnosed as soft tissue tumors or infected cysts. FNA can be diagnostic if unstained, refractile, intracellular mycobacteria are recognized on Romanowsky stained smears. Fite stain for Mycobacterium leprae confirms the diagnosis. Awareness of the differential diagnosis of skin nodules yielding foamy histiocytes on FNA, briefly discussed, should help avoid error.
瘤型麻风可出现皮肤结节，这些结节可能被误诊为软组织肿瘤或感染性囊肿。如果在罗曼诺夫斯基染色涂片上识别出未染色、有折光性的细胞内分枝杆菌，细针穿刺抽吸活检（FNA）可具有诊断价值。对麻风分枝杆菌的萋-尼氏染色可确诊。本文简要讨论了对FNA时产生泡沫状组织细胞的皮肤结节进行鉴别诊断的认识，这应有助于避免误诊。
