title: The immunohistochemical demonstration of Helicobacter pylori in rectal ectopia.
abstract: The finding of heterotopic gastric mucosa in the rectum is rare, with less than 40 reported cases in the literature. A condition of unknown etiology, several hypotheses exist including infectious and congenital. We report a case of ectopic gastric tissue in the rectum of a 47-year-old female, and her subsequent clinical course. Furthermore for the first time, we present immunohistologic evidence of the presence of Helicobacter pylori in rectal ectopic gastric tissue.
