Fine needle aspiration cytodiagnosis of subcutaneous sacrococcygeal myxopapillary ependymoma. A case report.
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.
