Primary malignant fibrous histiocytoma of the intestine: Intussusception of a rare neoplasm

Malignant fibrous histiocytoma, a tumor of mesenchymal tissue, is being reported with increased frequency. However, no cases of primary tumors involving the gastrointestinal tract have yet been described. This report documents a case in which the patient clinically manifested a colonic obstruction associated with intussusception. Following radical resection of the mass, close re-evaluation after one year has shown no evidence of tumor recurrence.
