We report a case of subglottic narrowing caused by an extranodal deposit of sinus histiocytosis in a 55-year-old man. To the best of our knowledge, no previous reports have described diagnosis using sonographic-guided fine-needle aspiration cytology for Rosai-Dorfman disease of the subglottis. This patient was diagnosed by sonographic-guided fine-needle aspiration biopsy, which revealed lymphocytes, plasma cells, and many foamy, multinuclear histiocytes with preserved lymphocytes in their cytoplasm (emperipolesis). The patient underwent an incisional biopsy of the tumor and received postoperative steroids and low-dose chemotherapy. The subglottic tumor was markedly regressed 6 months later.
我们报告一例55岁男性因窦组织细胞增生症的结外沉积导致声门下狭窄的病例。据我们所知，此前尚无关于使用超声引导下细针穿刺细胞学诊断声门下Rosai-Dorfman病的报道。该患者通过超声引导下细针穿刺活检确诊，结果显示淋巴细胞、浆细胞以及许多细胞质内含有保存完好淋巴细胞（血细胞吞噬现象）的泡沫状多核组织细胞。患者接受了肿瘤切除活检，并在术后接受了类固醇和低剂量化疗。6个月后，声门下肿瘤明显消退。
