Malignant fibrous histiocytoma of the colon associated with diverticulitis.

We report the second case of a malignant fibrous histiocytoma of the large bowel. The neoplasm constituted an incidental finding during the diagnostic work-up for diverticulitis of the sigmoid colon. There was a massive abdominal recurrence of the tumor four months after colectomy, and the patient died nine months after the initial operation. The literature on fibroblastic sarcomas of the colon is also reviewed.
