title: Ovarian mucinous cystadenocarcinoma with sarcoma-like mural nodules.
abstract: We present a rare case of a 31-year-old woman with a mucinous ovarian tumor with sarcoma-like mural nodules. The epithelial elements consisted of a mixture of benign, borderline-malignant, and mucinous adenocarcinoma; the sarcoma-like mural nodules consisted of pleomorphic and epulis-like cells. The lesion was resected for an ovarian tumor. In an immunohistochemical study, these cells stained for lysozyme and vimentin. The patient received 2 courses of cisplatin (100 mg/m2). There was no evidence of disease at a second-look laparotomy after 1 year, and none upon examination 6 years after the initial operation. The mural nodules might be of non-epithelial origin. The prognosis of patients with this rare lesion appears favorable, according to this and previous reports.
