GASTRIC INLET PATCH CONTAINING SUBMUCOSALLY INFILTRATING ADENOCARCINOMA

We describe a patient With an unusual segment of ectopic gash-ic mucos a in the proximal esophagus. The gastric heterotopia was circumferenti al and unusually long at 7 cm. It contained benign rugal-type folds. a stricture at the mid-portion of the gastric inlet patch was lined by normal antral-type gastric mucosa but harbored submucosally infiltrati ng adenocarcinoma. There was no evidence of Helicobacter pylori infect ion by biopsy or serologic screening. Malignancy, including submucosal ly infiltrating adenocarcinoma, should be considered in patients with strictures involving ectopic gastric mucosa in the proximal esophagus.
