Ectopic pancreas is most commonly found in the antrum of the stomach, duodenum, or proximal jejunum. Rarely ectopic pancreas in the proximal stomach has been reported. Moreover, the coexistence of two ectopic pancreases at gastric cardia and antrum in a patient has not been reported. Ectopic pancreas usually appears as a submucosal mass, and it is difficult to differentiate between ectopic pancreas and other common submucosal tumors, such as a gastrointestinal stromal tumor (GIST) or leiomyoma. Here, we present a case of the coexistence of two ectopic pancreases at cardia and antrum of the stomach in a 60-year-old man, which was preoperatively misdiagnosed as GIST.

  • Fig. 1 A 60-year-old man with synchronous ectopic pancreases in the gastric cardia and antrum. A. Coronal contrast-enhanced CT during the portal venous phase shows a well-defined heterogeneously enhancing submucosal mass (arrows) with a suspicious small cystic portion (asterisks) in the gastric cardia. The overlying mucosa appears to be intact (arrowheads). B. Coronal contrast-enhanced CT during the portal venous phase shows an ill-defined heterogeneously enhancing mass (arrows) with an endoluminal growth pattern in the greater curvature side of the gastric antrum. The internal cystic portion or overlying mucosa of it is not definite at CT. C. Endoscopy images show a submucosal mass with intact overlying mucosa in the gastric cardia (left), while the other submucosal mass with a focal shallow pit (arrow) at the overlying mucosa in the greater curvature side of the gastric antrum (right). D. EUS images of submucosal masses in the gastric cardia (left) and the other lesion on the greater curvature side of the gastric antrum (right) show indistinct, heterogeneous, and intermediate hypoechoic lesions with an internal anechoic cystic portion (asterisks). E. Photomicrograph shows heterotopic normal pancreatic tissues (asterisks) beneath the gastric mucosa, consisting of ectopic pancreas (H & E, ×100).
