Abstract

We experienced a case of malignant fibrous histiocytoma (MFH) causing intraabdominal hemorrhage in which hemostasis was accomlished by embolization and the tumor was successfully resected by an elective surgery. A 71-year-old woman was admitted to the hospital because of abdominal pain. There was a previous history of undergoing a radical histerectomy with excision of the bilateral ovaries for hysteromyoma 12 years before. The patient was taking an oral antihypertensive. On admission abdominal CT and ultrasonography revealed a pelvic tumor measured 7cm in diameter with intraabdominal hemorrhage. Four days later, hemorrhage from the tumor recurred and transcatheter embolization of internal iliac arteries was done by sponge. Ninteen days after the TAE, the tumor was resected. The tumor tended to bleed, was localized in the pelvic space, and derived from the left peritoneum. The section was solid. Pathologically storiform pattern and the presence of occasional pleomorphic giant cells and numerous mitotic figures were seen. The findings are consistent with those of MFH arising in the retroperitoneum. She was discharged from the hospital without postoperative complications, but a local recurrence was recognized five months after the surgery.
