Abstract
A 68-year-old woman who was admitted for epigastralgia was diagnosed as having gastric cancer. On the second day of the hospitalization, she suddenly developed massive hematemesis and hemorrhagic shock. We treated her with fluid resuscitation and blood transfusion, but her condition did not improve. Therefore, we decided to perform an emergency operation. The laparotomy findings showed that the tumor had invaded the pancreas and the gastroduodenal artery. A pancreaticoduodenectomy was performed because of uncontrolled bleeding from the invaded pancreas and the invaded gastroduodenal artery. The pathological examination revealed gastric malignant lymphoma (diffuse large B cell type), and the clinical stage was II 1E (pancreas). After her condition improved, she received chemotherapy in the hematological department.
