A case of recurrent and metastasizing myxopapillary ependymoma of the sacral region in a 35-yr-old man is reported. Fifteen years after the original diagnosis, he presented with an abdominal mass, subcutaneous nodules in the previous surgical excision line, and bilateral inguinal lymph node enlargement. FNA cytology of the inguinal lymph nodes showed a poorly cohesive, highly cellular smear pattern exhibiting papillary formations and rosette-like structures composed of slim columnar cells having cytoplasmic processes without evidence of atypia. Histologic and ultrastructural findings confirmed the diagnosis. Chromosomal analysis was also done.
报告了一例35岁男性骶骨区域复发性转移性黏液乳头状室管膜瘤。初次诊断15年后，他出现腹部肿块、既往手术切除线处的皮下结节以及双侧腹股沟淋巴结肿大。腹股沟淋巴结的细针穿刺抽吸活检（FNA）细胞学检查显示涂片模式细胞黏附性差、细胞丰富，呈现乳头结构和由具有胞质突起的细长柱状细胞组成的玫瑰花结样结构，无异型性证据。组织学和超微结构检查结果证实了诊断。还进行了染色体分析。
