The aim of this study was to present a case of enteric duplication cyst and criteria for a proper differential diagnosis. A 51-year-old male was hospitalized for pancreatic tail neoplasm and distal pancreatectomy with splenectomy was performed. During surgery, a jejunal cystic lesion was incidentally detected and jejunectomy was performed. Microscopically, the cyst was observed to be covered by Keratin 7/Keratin 20 positive intestinal type epithelium and the muscularis layer was shared by the cyst and adjacent jejunum, without a cleavage plane between the cyst wall and jejunal muscularis propria. In the deep muscularis propria, a Heinrich's type I ectopic pancreas was also noted. In the pancreatic tail, a low grade intraepithelial lesion (panIN-1a) was diagnosed. This case highlights the necessity for a correct differential diagnosis of such rare lesions. Roughly 30 cases of jejunal duplication cysts have been reported to date in the PubMed database.
本研究的目的是呈现一例肠重复囊肿病例以及正确鉴别诊断的标准。一名51岁男性因胰尾肿瘤住院，并接受了胰体尾切除术及脾切除术。手术过程中，偶然发现一个空肠囊性病变，遂进行了空肠切除术。显微镜下观察，囊肿被角蛋白7/角蛋白20阳性的肠型上皮覆盖，囊肿与相邻空肠共用肌层，囊肿壁与空肠固有肌层之间无分隔平面。在固有肌层深部，还发现了海因里希I型异位胰腺。在胰尾，诊断出低级别上皮内病变（胰腺上皮内瘤变-1a级，panIN-1a）。该病例凸显了对此类罕见病变进行正确鉴别诊断的必要性。截至目前，PubMed数据库中已报道了约30例空肠重复囊肿病例。
