  • Abstract
  • Look Inside

 Hemangiopericytoma is a relatively rare tumor originating from pericytes in organs. A 53-year-old woman was admitted to our hospital with sudden anemia and faintness. She had no history of gastrointestinal bleeding, but a fist-size tumor in the area around the gastric antral greater curvature was found. Subtotal gastrectomy was performed and it was shown that the tumor consisted of a 1.5 cm intramuscular tumor at the antrum and a 4 cm tumor with hematoma at the antral greater curvature. The tumor was histologically diagnosed as hemangiopericytoma by using the silver impregnation method for detecting silver staining fibers and the electron microscope. Recurrence has not been noted for 43 months. Up to date, 18 cases of hemangiopericytoma originating from the stomach have been reported in Japan, but there has been no case known to have caused anemia due to intratumoral bleeding.
