The ectopic pancreas is often observed in the gastrointestinal tract, and is typically asymptomatic. A 28-year-old woman was referred to our hospital following repeated vomiting after every meal. Following gastroscopy, contrast-enhanced computed tomography (CE-CT), and endoscopic ultrasonography (EUS), she was diagnosed with gastric outlet obstruction, also known as pyloric obstruction, caused by a giant submucosal cystic tumor. The condition was successfully treated with EUS-guided cystic drainage, and she was diagnosed with a cystic tumor originating from the ectopic pancreas. The tumor shrank following EUS-guided cystic drainage, and her obstructive symptoms resolved. In cases with overgrowth of the ectopic pancreas, the differential diagnosis of malignancy is important but challenging. Herein, we report a unique final pathology of this rare case and discuss the findings with a literature review.
异位胰腺常出现在胃肠道，通常无症状。一名28岁女性因每餐饭后反复呕吐被转诊至我院。经胃镜检查、增强计算机断层扫描（CE-CT）和内镜超声检查（EUS）后，她被诊断为胃出口梗阻，也称为幽门梗阻，由巨大的黏膜下囊性肿瘤引起。该病症通过EUS引导下的囊肿引流成功治愈，她被诊断为起源于异位胰腺的囊性肿瘤。EUS引导下的囊肿引流后肿瘤缩小，她的梗阻症状得以缓解。在异位胰腺过度生长的病例中，恶性肿瘤的鉴别诊断很重要但具有挑战性。在此，我们报告这一罕见病例独特的最终病理结果，并结合文献复习讨论这些发现。
