Case report examines gastric heterotopic pancreas mimicking a submucosal tumor, highlighting diagnostic importance.
Gastric heterotopic pancreas (HP) often mimics submucosal tumors like GISTs on imaging. Multidisciplinary integration of endoscopy, EUS‐FNA, and histopathology is essential to avoid misdiagnosis. For symptomatic HP, minimally invasive resection is curative; asymptomatic cases require long‐term surveillance due to malignant potential.
