A case of malignant mixed mesodermal tumor of the ovary in a postmenopausal patient presenting with abdominal distension is reported. Cytologic examination of smears of the ascitic fluid showed the presence of adenocarcinomatous and sarcomatous cells (with some of the latter being giant cells) plus numerous unidentifiable cells that bore some resemblance to either mesothelial cells or macrophages. Electron microscopic studies showed a clear differentiation of the adenocarcinomatous and sarcomatous cells from positively identified mesothelial cells and macrophages also present in the ascitic specimen, indicating that the unidentified cells in fact originated in the adenocarcinoma (endometrioid carcinoma), chondrosarcoma and unclassified sarcoma found in the surgical specimen. The differential diagnostic cytomorphologic and electron microscopic features are described in detail.
报告了一例绝经后卵巢恶性中胚叶混合瘤患者，该患者以腹胀为表现。对腹水涂片进行细胞学检查发现存在腺癌和肉瘤细胞（后者部分为巨细胞），以及许多无法识别的细胞，这些细胞与间皮细胞或巨噬细胞有一些相似之处。电子显微镜研究显示，腹水标本中存在的腺癌和肉瘤细胞与已明确鉴定的间皮细胞和巨噬细胞有明显区别，表明这些无法识别的细胞实际上起源于手术标本中发现的腺癌（子宫内膜样癌）、软骨肉瘤和未分类的肉瘤。详细描述了鉴别诊断的细胞形态学和电子显微镜特征。
