Primary inflammatory malignant fibrous histiocytoma of the colon.

A unique case of inflammatory malignant fibrous histiocytoma of the large bowel is presented. This lesion occurred in the colon of an elderly man suffering from weakness, anemia, anorexia, and weight loss. A right hemicolectomy was performed, and six months later, on follow-up, he was found to be well. The literature on visceral involvement by malignant fibrohistiocytic tumors is reviewed.
