BACKGROUND: Malignant fibrous histiocytoma (MFH) in the large bowel, which is composed of spindle-shaped cells arranged in a pleiomorphic and storiform pattern, is an extremely rare tumor. METHODS: We in this study report on a case of a 73-year-old man with a sarcoma arising from a diverticular sigmoid without any signs of involvement of regional lymph nodes or metastasis to liver or the abdomen. RESULTS: A sigmoid resection was performed with an uneventful postoperative course. Microscopically, the tumor consisted of bundles of spindle-shaped and pleiomorphic multinucleated cells without differentiation characteristics for other tumors than MFH. SUMMARY: Since the late 1970s, only 22 case reports of colorectal MFH have been documented, and little is known about its histogenesis and optimal treatment. A review of the cases and the world literature on immunohistochemistry and treatment is given.
