Although ectopic gastric mucosa is often mentioned as a source of upper esophageal adenocarcinoma, few such cases have actually been documented. We report two cases and offer a review of the literature. Ectopic gastric mucosa in the upper esophagus is a relatively common congenital condition, but the risk of malignant transformation is extremely low. Ectopic gastric mucosa should be distinguished from Barrett's esophagus, an acquired condition with a well-documented predilection for developing adenocarcinoma.
尽管异位胃黏膜常被提及是食管上段腺癌的一个来源，但实际上仅有少数此类病例有文献记载。我们报告两例病例并对文献进行综述。食管上段的异位胃黏膜是一种相对常见的先天性疾病，但其恶变风险极低。异位胃黏膜应与巴雷特食管相鉴别，巴雷特食管是一种后天性疾病，其发生腺癌的倾向有充分文献记载。
