BACKGROUND
Heterotopic gastric mucosa (HGM) is commonly seen in the upper esophagus during endoscopyand is generally considered a benign disease. A hyperplastic polyp and an adenocarcinoma arising in heterotopic gastric mucosa are quite rare occurences.
CASE PRESENTATIONS
We present two cases: The first is a patient who suffered from dysphagia because of a large hyperplastic polyp that arose from HGM; the polyp was excised endoscopically. Secondly, we report a rare case of adenocarcinoma arising in HGM of the cervical esophagus.
CONCLUSION
Morphologic changes or malignant transformation can develop in the inlet patch. Therefore, gastroenterologists should be aware of the possibility of HGM just distal to the upper esophageal sphincter.
背景
内镜检查时，异位胃黏膜（HGM）在上段食管较为常见，通常被认为是一种良性疾病。在异位胃黏膜中发生增生性息肉和腺癌的情况相当罕见。
病例报告
我们展示两个病例：第一个病例是一名患者因源于HGM的巨大增生性息肉而出现吞咽困难，该息肉通过内镜切除。其次，我们报告一例发生在颈段食管HGM中的腺癌罕见病例。
结论
入口斑可能会发生形态学改变或恶变。因此，胃肠病学家应意识到食管上括约肌远端存在HGM的可能性。
