A 78-year-old woman admitted for an intra abdominal tumor was found in computed tomography to have a 18 cm tumor in the right hypochondrium and a metastatic tumor of the lateral liver lobe. Endoscopic examination showed no mucosal lesion. We suspected a mesenchymal tumor with liver metastasis. The tumor grew extraluminally from the posterior wall of the stomach and was fed by the right gastric and gastro epiploic arteries. Distal gastrectomy with B-II reconstruction was done. The tumor was diagnosed as well-differentiated liposarcoma of the stomach. Primary gastric liposarcoma is rare and only 29 cases have been described in the English and Japanese literature. Although liposarcoma is considered to have a good prognosis, primary gastric liposarcoma with hepatic metastasis have a poor prognosis.

Key words
