Adenomas arising in Barrett's esophagus with adenocarcinoma. Report of three cases.
Adenocarcinoma of the esophagus is a well known complication of Barrett's esophagus, and results from a dysplasia-carcinoma sequence. This report describes 3 patients with adenomatous polyps arising in Barrett's esophagus. One patient presented with multiple sessile or pedunculated polyps giving a polyposis appearance; the other two patients had single polyps associated with distinct adenocarcinoma arising in Barrett's esophagus. Polyps consisted of adenomatous proliferation with adenocarcinoma in the 3 patients. Review of the literature identified twelve previously reported cases. These cases show that although rare, adenomas may arise in Barrett's esophagus, and are most likely premalignant lesions such as other adenomas of the gastrointestinal tract.
