Abstract

A 74-year-old man presented with intestinal obstruction. CT (computed tomography) revealed a 25-mm mass in the proximal jejunum. Double-balloon endoscopy (DBE) identified a smooth, asymmetrically localized mass with oozing and luminal stenosis covered with the mucosa of swollen villi. Small bowel radiography demonstrated jejunal obstruction. Histopathological examination of the resected specimen confirmed moderately differentiated adenocarcinoma arising from ectopic pancreatic tissue of Heinrich type I. Our case suggests that cancer arising from ectopic pancreas should be considered as a candidate diagnosis of a submucosal tumor in the jejunum.

摘要

一名74岁男性因肠梗阻就诊。计算机断层扫描（CT）显示空肠近端有一个25毫米的肿块。双气囊小肠镜检查（DBE）发现一个表面光滑、位置不对称的肿块，有渗血及管腔狭窄，表面覆盖着肿胀绒毛的黏膜。小肠造影显示空肠梗阻。对切除标本的组织病理学检查证实为起源于海因里希I型异位胰腺组织的中分化腺癌。我们的病例提示，起源于异位胰腺的癌症应被视为空肠黏膜下肿瘤的候选诊断。
