A 58-year-old @entity1 was transferred to us from his local hospital because of failure to control his @entity360 by endoscopic hemostasis. Abdominal imaging suggested a hypervascular @entity5 of the pancreatic head (36  mm diameter), and laboratory testing showed an elevated serum @entity8243 level (17,800  pg/mL). Gastroduodenal endoscopy revealed @entity4773 from the ampulla of Vater. The selective arterial secretagogue injection test suggested a @entity7581 in the pancreatic head, but no @entity7581 in the pancreatic tail. The @entity1 was diagnosed with solitary pancreatic head @entity7581 complicated by hemosuccus pancreaticus, and pancreaticoduodenectomy was performed. Intraoperatively, the diagnosis was changed to primary @entity1600 without pancreatic involvement. The @entity360 stopped postoperatively and serum @entity8243 levels returned to normal. Histological examination of the surgical specimens revealed a small @entity7581 in the duodenum (7  mm diameter). The final diagnosis was microgastrinoma of the duodenum with peripancreatic lymph node @entity3 . The cause of @entity548 from the ampulla of Vater was initially obscure, but eventually a @entity548 with moderate atypia was found in the common bile duct, indicating @entity5 ( @entity5 ). This is the first report of @entity7252 due to @entity5 with @entity7581 .
