A 39-year-old woman was found to have intrapelvic tumor and multiple liver metastases by abdominal computed tomography. Although laparotomy was done under the diagnosis of ovarian cancer with liver metastases, the histological diagnosis of the tumor during the operation was jejunal leiomyosarcoma. Only the primary lesion was removed at the same time. Three weeks later, right lobectomy of the liver and catheterization of the hepatic artery and the portal vein were carried out for liver metastases. Following the procedure, intra-arterial and intra-portal vein infusion chemotherapy of epirubicin was performed every 2 weeks. The patient has been well for 1 year and 11 months with complete remission.
