  • Abstract
  • Look Inside

The patient of a 60 years old woman complained of the left upper abdominal pain. Barium enema showed a stenosis in the proximal descending colon. Endoscopical examination showed a marked stenosis but no remarkable changes of the mucosa in this portion. By exploratory laparotomy, a tumor was found in the descending colon near the splenic flexure. There was no evidence of regional or distant metastasis, so complete excision was performed. On the resected specimen, the tumor measured 6×3.2×1.4cm and cut surface of the tumor was yellowish-white. Microscopically the tumor was situated mainly in the subserosa and histological diagnosis was malignant fibrous histiocytoma.

There was a massive right retroperitoneal recurrence of the tumor six months after the removal, and the patient died three years and a half after the initial operation. Malignant fibrous histlocytoma is a primitive mesenchymal tumor frequently found in the soft tissues of the extremity and retroperitoneum.

Only four previous reports of this lesion of the gastrointestinal tract are present in the medical literature, and we report the fifth case.
