Hemangiopericytoma was first reported by Stout et al. in 1942, as a neoplasm which originated from pericytes. A case of hemangiopericytoma originating from the stomach an extremely rare neoplasm, is reported. Only 16 cases, including this case, have been reported in Japan. A 74-year-old man was admitted to our hospital with a complaint of abdominal mass. A UGI series revealed a lesion like a submucosal tumor at the greater curvature of the stomach. Abdominal US and CT scan showed the tumor with a cyst in the left upper abdominal area. Angiography demonstrated that the tumor was supplied by the right gastric artery. Laparotomy was performed. The tumor was covered by the major omentum and continued from the gastric wall. There was no adhesion around the tumor and no invasion to other organs, the regional lymph nodes were not affected. The tumor was histologically diagnosed as hemangiopericytoma. Recurrence and metastasis have not been noted for 14 months.
