    Author: Wang H, Tan Y, Liu D.
    Journal: Rev Esp Enferm Dig; 2019 Sep; 111(9):712-713. PubMed ID: 31368344.
    Abstract:
    To the best of our knowledge, this is the first report of ectopic gastric mucosa appearing between muscularis mucosae and submucosa, at esophagogastric junction. Currently there are two theories explaining the mechanism. The most widely accepted one is that Ectopic gastric mucosa is an embryological remnant, and an alternative theory is abnormal proliferation under inflammation1.Although we don't have many evidences to clarify this case into specific mechanism mentioned above, Nomura et reported two cases of Adenocarcinoma of the cervical esophagus arising from ectopic gastric mucosa, Completely resected by ESD with no signs of recurrence2. Therefore, In this present case, the lesion was successfully managed with ESD. The symptoms were released after the operation and the patient remained well during a year follow-up. Long-term follow-up is recommended in case of recurrence or gastric cancer.
