title: Adenocarcinoma arising in Barrett's esophagus with Zollinger-Ellison syndrome.
abstract: A 61-year-old man with a 20-year history of recurrent gastric peptic ulcerations had an adenocarcinoma of the esophagus resected. The carcinoma was associated with columnar cell-lined (Barrett's) esophagus with carcinoma in situ. The patient had hypergastrinemia (gastrin level, 1,000 pg/dl), and at autopsy two months after the operation, a 3-mm pancreatic adenoma was discovered. In addition to the rarity of this clinical constellation, the case is of interest in suggesting that hypergastrinemia does not protect against peptic esophagitis and its sequelae.
