SUMMARY Malignant fibrous histiocytoma (MFH) represents a soft tissue sarcoma originating from fibroblast cells, and is characterized by a high rate of metastasis or recurrence. The development of this tumor in the gastrointestinal tract is a very rare entity. No more than 30 cases are described in the litrature. We report on a case of such tumor of the abdominal cavity in a 45 year-old woman, presented with epigastric pain, anorexia and weight loss. The CT-scanning revealed the presence of multiple solid tumors in the peritoneal cavity. On the exploratory laparotomy at least 15 solid whitish tumors were found, attached to the wall of the small intestine, as well as to the parietal peritoneum. In addition, there were three metastases revealed in the liver. All tumors were excised; most of them were about 10 cm in diameter. The histopathologic study indicated the presence of a stromal tumor consisting of spindle cells. The consequent immuno- histo-chemical examination of the resected specimens established the definite diagnosis of a pleomorphic malignant fibrous histiocytoma. The postoperative course of the patient was uneventful. She received adjuvant chemotherapy and is still alive and in good health two years later. Key words: malignant fibrous histiocytoma, soft tissue tumors, stromal tumors, sarcomas, storiform-pleomorphic lesions. (EN)
