A tumor located subcutaneously over the coccyx of a 32-year-old woman was diagnosed by fine needle aspiration (FNA) cytology as a myxopapillary ependymoma originating in the soft tissue. The FNA smears showed characteristic papillary structures, consisting of a central mucinous core surrounded by cuboidal-to-columnar cells, and scattered ependymal cells. The excised tumor was connected to neither the filum terminale nor the cauda equina. Histopathologic study confirmed the cytologic findings.
一名32岁女性尾骨皮下的肿瘤经细针穿刺（FNA）细胞学检查诊断为起源于软组织的黏液乳头状室管膜瘤。FNA涂片显示特征性乳头结构，由中央黏液核心和周围的立方到柱状细胞以及散在的室管膜细胞组成。切除的肿瘤与终丝和马尾均无连接。组织病理学研究证实了细胞学检查结果。
