Description
Here we report a metastatic brain carcinosarcoma from the uterus that posed a problem on diagnosis by containing an extensive gliomatous component. A 56-year woman developed motor aphasia 3 months after hysterectomy for a uterine tumor. Magnetic resonance imaging (MRI) demonstrated a left frontal cystic tumor, which was treated by stereotactic radiosurgery. The lesion recurred 5 months later and was resected. Histological examination demonstrated neoplastic cells that were positive for glial fibrillary acidic protein (GFAP), leading to the diagnosis of high-grade glioma. This lesion recurred again after 9 months, and was resected again. The tumor tissue mostly consisted of GFAP-positive gliomatous cells, but close examination identified a sarcomatous component compatible with the metastatic lesion from the uterine sarcoma. This sarcoma component contained GFAP-negative– CD10-positive cells and GFAP-positive–CD10-negative cells. There was no clear border between those components, and, therefore, the lesion was considered to be a metastatic tumor from the uterus showing extensive neural differentiation. Although rare, uterine tumors are known to show such neural differentiation, and the histological diagnosis in such cases can be challengin
