Abstract
A 55-year-old woman underwent a curative operation after diagnosis of a soft tissue sarcoma in the right upper thigh. Based on a definitive diagnosis of malignant fibrous hisciocytoma (MFH) by pathology, postoperative chemotherapy was performed. After 23 months, bilateral pulmonary metastasis was detected by CT. Resection of bilateral lung masses was scheduled, but melena appeared, and then anemia. A tumor found at the ileocecal junction by colonoscopy. The tumor was biopsied, and elective surgery was scheduled after close evaluation. However, obstructive intestinal symptoms such as vomiting etc. appeared, immediately. She was introduced to our division, and an urgent laparotomy was done. There were two lesions in the intestine: one was in the jejunum and the other in the ileum. In addition, the jejunum lesion had caused intussusception. Excision of the small intestine was performed for these two lesions. We finally established a diagnosis of relapse of MFH by the pathological immunostaining findings and comparison with the pathological findings of the initial lesion. There are few operationed cases of metastasis to the intestinal tract from outside the stomach, and the cases presenting intussusception are particularly rare. We described this case and reviewed the pertinent literature.
