Abstract

Pancreatic rest/ectopic pancreas is a rare condition. An 82-year-old male presented with abdominal pain and was found to have an antral nodule on esophagogastroduodenoscopy (EGD). An endoscopic ultrasound (EUS) was done and the nodule was resected. Histology showed ectopic pancreatic tissue with pancreatic intraepithelial neoplasia, PanIN-1 (low-grade dysplasia). This case highlights the importance of considering pancreatic rest as a differential in patients who present with a gastric sub-epithelial lesion and the associated finding of PanIN-1 highlights the importance of resecting such heterogeneous appearing lesions given the potential risk of progressing to pancreatic ductal adenocarcinoma (PDA).
