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."

In endoscopic studies, HGM patches are found in 0.1-10% of the cases, but frequency tends to be clinically underestimated...... The region is quickly passed protruding the endoscopoe over the sphincter's resistance and only by gently withdrawing the instrument can an inlet patch be detected.

The columnar epithelium of the embry's esophagus is generally replaced by squamous cell epithelium. This process starts in the midesophagus and extents vertically in both directions with the cervical esopahgus being the last region to get stratified. If the squamous epithelization remains incomplete, the persisting columnar-lined area differentiates to HGM.

The low frequency of malignant transformation of HGM in the cervical esophagus as compared to Barrett's esophagus in the distal esophagus suggests that it may not be regarded as a premalignant lesion. Malignant procression of HGM is - compared to its high prevalence - an exceedingly rare and sporadic event.
