BACKGROUND
Heterotopic pancreas is a rare congenital condition characterised by pancreatic tissue lacking vascular or anatomic communication with the normal pancreas. Most cases of ectopic pancreas are asymptomatic. The preoperative diagnosis of this condition is difficult.
CASE PRESENTATION
A 50-year-old woman presented with dyspeptic symptoms of 4 years duration. Contrast enhanced CT (computed tomography) scan of abdomen suggested a gastrointestinal stromal tumour in the fundus of the stomach. The patient underwent laparoscopy assisted resection and subsequent histology revealed ectopic pancreatic tissue.
CONCLUSION
Although heterotopic pancreas is a rare lesion diagnosed on histology, it should be considered in the differential diagnosis of gastric mass lesions and in patients presenting with vague upper gastrointestinal symptoms.
背景
异位胰腺是一种罕见的先天性疾病，其特征是胰腺组织与正常胰腺之间缺乏血管或解剖学联系。大多数异位胰腺病例无症状。这种疾病的术前诊断困难。
病例介绍
一名50岁女性出现了持续4年的消化不良症状。腹部增强CT扫描提示胃底有一个胃肠道间质瘤。患者接受了腹腔镜辅助切除术，随后的组织学检查显示为异位胰腺组织。
结论
尽管异位胰腺是一种经组织学诊断的罕见病变，但在胃肿块病变的鉴别诊断以及出现不明原因上消化道症状的患者中应考虑到该病。
