Barrett's esophagus is a metaplastic process in which the squamous epithelium of the lowet esophagus is replaced by columnar epithelium. Most cases are believed to be related to prolonged gastroesophageal reflux. Detection of Barretts esophagus is important in that it results in adenocarcinoma in about 10% of patients. We report a case of adenocarcinoma arising from Barrett's esophagus in a 56 year-old man, diagnosed incidentally at a physical check-up. Grossly, the esophagogastric junction was irregular and there were two small ulcers in the lower esophagus. Microscopically, ihe squamous epithelium of the lower hagus was replaced by specialized intesinal mucosa with a small focus of adenocarcinona confined to the submucosa in one area. Many separate dysplastic foci were also present in the nearby esophageal mucosa. (Korean J Gastrointest Endosc 17: 151-154, 1997)
