INTRODUCTION
Gastric heterotopic pancreas (HP) is usually asymptomatic and benign; however, it may become evident when it is complicated by pathological changes such as inflammation, bleeding, and malignant transformation.
PRESENTATION OF CASE
A 43-year old man was diagnosed with gastric HP 18 years prior suffered a haemorrhage from the enlarged gastric HP with multiple cystic lesions. Although endoscopic ultrasonography-guided fine needle aspiration showed no malignancy, he underwent a partial gastrectomy for diagnosis and treatment. Postoperative histological findings revealed ectopic pancreatic tissue with retained cysts that consisted of dilated pancreatic ducts without malignancy.
DISCUSSION
This is a first report of enlarged gastric HP due to the expansion of retained cysts. Gastric HP is rarely enlarged by pathological changes including inflammation, retention cysts, or malignant neoplasms.
CONCLUSION
Symptomatic enlarged gastric HP should be respected and further examined histologically to ensure diagnostic accuracy.
引言
胃异位胰腺（HP）通常无症状且为良性；然而，当它并发炎症、出血和恶性转化等病理变化时可能会变得明显。
病例介绍
一名43岁男性18年前被诊断为胃HP，因胃HP肿大并伴有多个囊性病变而出血。尽管内镜超声引导下细针穿刺活检未发现恶性肿瘤，但他接受了胃部分切除术以进行诊断和治疗。术后组织学检查发现异位胰腺组织伴有潴留性囊肿，囊肿由扩张的胰管组成，无恶性肿瘤。
讨论
这是关于因潴留性囊肿扩张导致胃HP肿大的首例报告。胃HP很少因包括炎症、潴留性囊肿或恶性肿瘤在内的病理变化而肿大。
结论
对于有症状的肿大胃HP应予以重视，并进行进一步的组织学检查以确保诊断准确性。
