Diagnosis of ectopic pancreas by endoscopic ultrasound with fine-needle aspiration

Figure 1 Esophagogastroduodenoscopy and endoscopic ultrasound evaluation of gastric ectopic pancreas. A: Esophagogastroduodenoscopy image showing subepithelial lesions (SEL) in the antrum with overlying dimple (arrow); B: Endoscopic ultrasound image showing gastric SEL with intra-lesional duct (arrow).
