    Abstract:
    This patient was a 96-year-old woman. She was referred to our hospital with abdominal pain and vomiting. The levels of the tumor markers CEA and CA19-9 were elevated, at 39.47 ng/mL and 918.5 U/mL, respectively. She was diagnosed with peritonitis with digestive tract perforation by abdominal CT and an emergency operation was performed. At laparotomy, dirty ascites was observed in the peritoneal cavity. A perforation, 1 cm in diameter was found in the jejunum 15 cm from the Treitz ligament, and a mass, 2 cm in diameter was also palpated on the mesentery side. We performed jejunectomy including the tumor. The submucosal tumor was 2 cm in size and the mucosal surface of the perforation was ulcerated. Pathohistological inspection of the extracted sample revealed no heteromorphism in the small intestine mucosal plane. A moderately differentiated adenocarcinoma was diagnosed in the submucosal layer of the heterotopic pancreas of Heinrich typeⅡ. No tumor cells were found in the perforation. Thirteen previous cases of ectopic pancreatic cancer have been reported and this was the 14th case.
