Core Tip
Core tip: Subepithelial lesions (SEL) of the upper gastrointestinal (GI) tract are common incidental findings during GI endoscopy. Ectopic pancreas (EP) is an uncommon yet innocent SEL that should be differentiated from premalignant lesions such as gastrointestinal stromal tumors or neuroendocrine tumors. Noninvasive studies such as computed tomography, magnetic resonance imaging, or standard mucosal biopsies cannot reliably diagnose EP, so the role of endoscopic ultrasound-fine-needle aspiration (EUS-FNA) was studied. Herein the endoscopic, endosonographic, cytologic, and histologic features of EP are presented along with a summary of the pertinent, existing literature. Our data support the conclusion that EUS-FNA is a safe and effective diagnostic tool for EP.
