Duplication cysts are uncommon congenital malformations that may occur anywhere throughout the alimentary tract. The stomach is an extremely rare site of occurrence. Here, we report a case of gastric duplication cyst initially presenting with a gastric submucosal tumor. A 28-year-old man complained of dyspepsia lasting 1 year and upper endoscopy revealed an ellipsoid submucosal tumor at the greater curvature of the antrum. We intended to use the injection-and-cut technique: however, after saline injection, the lesion was dented and impossible to grasp with a snare. Therefore, we decided to perform endoscopic submucosal dissection and removed the tumor without complication. Histopathology revealed a 0.6×0.6 cm-sized duplication cyst, and there has been no recurrence in 2 years.
重复囊肿是一种罕见的先天性畸形，可发生于整个消化道的任何部位。胃是极其罕见的发病部位。在此，我们报告一例最初表现为胃黏膜下肿瘤的胃重复囊肿病例。一名28岁男性主诉消化不良持续1年，上消化道内镜检查发现胃窦大弯处有一个椭圆形黏膜下肿瘤。我们原打算采用注射切除技术；然而，注射生理盐水后，病变出现凹陷，无法用圈套器抓取。因此，我们决定进行内镜黏膜下剥离术，顺利切除肿瘤且无并发症。组织病理学检查显示为一个0.6×0.6厘米大小的重复囊肿，两年内未复发。
