title: Giant heterotopic gastric polyp in the jejunum.
abstract: Polypoid lesions composed of gastric mucosa in the jejunum are rare. The vast majority of cases of ectopic gastric tissue occur in the duodenum. In this article, we present a case of heterotopic gastric mucosa forming a giant polyp in the mid jejunum. A review of the literature is presented, and the clinical and pathologic features of this unusual lesion are discussed.
