This report deals with a case a tumor in 60-year-old male who was admitted to our hospital with a complaint of an abdominal tumor. The tumor, 17×16×11cm arising from the wall of the jejunum at a distance of 10cm from Treitz ligamentum, weighted 1, 850g and contained about 1, 000cc of necrotic substance. The tumor was diagnosed as leiomyosarcoma of the jejunum. According to the literature, leiomyosarcomas of the small intestine are mostly found in the upper jejunum, especially from Treitz ligamentum to a distance of 60cm. The size of the tumor was 15cm or less in 73% of the cases, and tumors over 15cm were found in 25 cases. We found it difficult to diagnosis leiomyosarcoma of jejunum and to distinguish it from leiomyoma preoperatively. The effective therapy is to excise the tumor completely, and longterm follow-up is necessary because of recurrence in both the early period and after 5 years postoperatively.
