The malignant transformation of an ectopic pancreas in the duodenum is extremely rare. Herein, we report a case of an adenocarcinoma that arose from an ectopic pancreas. We also reviewed 14 cases of malignant transformations arising from an ectopic pancreas in the duodenum that were previously published.
An 81-year-old man with a 1-month history of vomiting was admitted to our institution. Esophagogastroduodenoscopy (EGD) and computed tomography (CT) scans revealed an obstruction at the first part of the duodenum. A distal gastrectomy was performed for diagnostic and therapeutic purposes. The histopathological examination of the resected specimen showed adenocarcinoma that arose from an ectopic pancreas (Heinrich type 1). The patient is alive without relapse at 18 months of follow-up.
Adenocarcinoma that arises from an ectopic pancreas should be considered when an obstruction is identified in the duodenum.
十二指肠异位胰腺的恶性转化极为罕见。在此，我们报告一例起源于异位胰腺的腺癌病例。我们还回顾了先前发表的14例十二指肠异位胰腺发生恶性转化的病例。
一名有1个月呕吐病史的81岁男性入住我院。食管胃十二指肠镜检查（EGD）和计算机断层扫描（CT）显示十二指肠第一部梗阻。为诊断和治疗目的进行了远端胃切除术。切除标本的组织病理学检查显示腺癌起源于异位胰腺（海因里希1型）。随访18个月时患者存活且无复发。
当十二指肠发现梗阻时，应考虑异位胰腺起源的腺癌。
