title: [Suspected malignant cancer of the pancreas associated with pseudo-invasive duodenal hamartomas in a patient with Peutz-Jeghers syndrome].
abstract: A 29-year-old man with a previously known Peutz-Jeghers syndrome (PJS) was admitted for epigastric pain, emesis and weight loss due to both intestinal intussusception causing bowel obstruction and obstructive pancreatitis. The patient had cholestasis with an enlarged common bile duct on imaging. Because duodenal and/or pancreatic cancer was suspected due to weight loss, the pancreatic and bile duct obstruction, and the increased risk of small intestine and pancreatic adenocarcinoma in patients with PSJ, a pancreatoduodenectomy was performed. Pathological examination revealed a duodenal polyp with epithelial misplacement invading the ampulla and compressing the main bile duct. Twenty months after surgery, there was no relapse of symptoms or cholestasis. This is the first case showing a direct role of pseudo-invasive duodenal harmatomas in the development of biliary obstruction and chronic obstructive pancreatitis.
