초록
Heterotopic pancreas in the stomach is usually asymptomatic and benign. Here, we presented a rare case of an early gastric canceroverlying a heterotopic pancreas. A 48-year-old woman underwent esophagogastroduodenoscopy, which revealed a subepithelial massmeasuring 2.0×1.5 cm on the gastric antrum with a 1-cm erosive erythematous discoloration on the surface. A biopsy specimen showedmoderately differentiated tubular adenocarcinoma. Endosonography showed a heterogeneous hypoechoic mass measuring 1.3×0.6 cm,with indistinct margins in the second and third layers of the gastric wall; anechoic tubular structures within the mass were suggestive ofheterotopic pancreas. Distal gastrectomy was performed, which confirmed an early gastric cancer confined to the mucosa, and a separateunderlying heterotopic pancreas. Although heterotopic pancreas is most likely benign, careful endoscopic observation of the mucosalsurface is necessary to avoid overlooking a coincident early gastric cancer.
Abstract
Heterotopic pancreas in the stomach is usually asymptomatic and benign. Here, we presented a rare case of an early gastric canceroverlying a heterotopic pancreas. A 48-year-old woman underwent esophagogastroduodenoscopy, which revealed a subepithelial massmeasuring 2.0×1.5 cm on the gastric antrum with a 1-cm erosive erythematous discoloration on the surface. A biopsy specimen showedmoderately differentiated tubular adenocarcinoma. Endosonography showed a heterogeneous hypoechoic mass measuring 1.3×0.6 cm,with indistinct margins in the second and third layers of the gastric wall; anechoic tubular structures within the mass were suggestive ofheterotopic pancreas. Distal gastrectomy was performed, which confirmed an early gastric cancer confined to the mucosa, and a separateunderlying heterotopic pancreas. Although heterotopic pancreas is most likely benign, careful endoscopic observation of the mucosalsurface is necessary to avoid overlooking a coincident early gastric cancer.
