Heterotopic gastric mucosa (HGM) is frequent in the cervical esophagus, but most carriers are asymptomatic. Nevertheless it can be responsible for local morphologic alterations (e.g., webs, strictures, ulcers, fistula) causing local symptoms (especially pain and dysphagia). Furthermore, in exceedingly rare cases, HGM can be the origin of malignant progression to cervical esophageal adenocarcinoma.

HGM is not exclusively found in the esophagus as it has also been described in other localizations throughout the gastrointestinal tract, like the tongue, the duodenum, the jejunum, the gall bladder, and the rectum.

The extent of HGM can vary from tiny microscopic foci to macroscopically visible area of red or salmon-colored velvety patches. Predominant localization of esophageal HGM is the region immediately below the upper esophageal sphincter. Such patches of macroscopically visible HGM are also called "inlet patches."
