A 68-year-old man visiting a neighborhood clinic with a history of epigastric pain and generalized fatigue was diagnosed as having anemia and referred to our hospital for further examination. Abdominal computed tomography revealed a tumor in the small intestine and invagination caused by the tumor. Colonoscopy also showed an ileal tumor. Histologically, the findings of the biopsy specimen were consistent with the diagnosis of leiomyosarcoma of the small intestine. The invaginated small intestine involving tumor was surgically resected. The tumor cells were immunohistochemically positive for desmin and α SMA; the tumor showed a high Ki 67 index. The tumor was finally diagnosed as leiomyosarcoma of the small intestine. There has been no local or distant recurrence until date, 28 months after the surgery.
