In this case, Esophagogastroduodenoscopy showed an approximately 25-mm diameter annular and polypoid mucosa at the opposite side of Pylorus ring in first part of duodenum. The biopsy specimens were diagnosed with the heterotopic gastric mucosa (HGM) pathologically. This is a rare presentation of annular and polypoid HGM in duodenum. This may indicate the needs for other documents as well as analysis regarding the mechanism for the development of HGM in duodenum.
在这种情况下，食管胃十二指肠镜检查显示在十二指肠第一部幽门环对侧有一个直径约25毫米的环形息肉样黏膜。活检标本经病理诊断为异位胃黏膜（HGM）。这是十二指肠环形息肉样HGM的一种罕见表现。这可能表明需要其他文献以及对十二指肠HGM发生机制的分析。
