A 62-year-old woman was evaluated for complaining of painless rectal bleeding. Digital examination revealed a rectal mass. Barium enema showed a wide-spread lesion with spiculation and shaggy nap shadow on the rectum. Rectal biopsy revealed malignant lymphoma.<BR>Upper gastrointestnal endoscopy revealed ulcer with irregular margin suggesting gastric cancer in the posterior wall of the gastric body. She was diagnosed as malignant lymphoma of the stomach by biopsy.<BR>By chmotherapy of lsophosphamide (40 mg/kg, 5days), gastric lesion disappeared completely and massive protrusion of the rectum decreased dramatically.<BR>As each lesion existed independently, the origin of malignant lymphoma might be multicentric in this case. This is believed to be a rare case with simultaneous development of gastric and rectal lymphoma.
