title: Ectopic gastric mucosa in the lower esophagus, presenting as a sessile polyp.
abstract: A patient with dysphagia caused by a sessile polyp in the lower esophagus is reported. Histologic examination showed ectopic gastric mucosa. Of the benign tumors of the esophagus, only leiomyoma is seen regularly. The remaining tumors are so rare that the consequences of this diagnosis are unclear. When symptoms make treatment necessary, local excision is preferred.
