Core Tip
Core tip: Heterotopic pancreas is usually considered a benign disease. We here present a rare case of heterotopic pancreas in the stomach with malignant change in a middle-aged female patient. Endoscopy revealed a protruding lesion in the gastric antrum which caused gastric outlet obstruction. The malignant transformation was not diagnosed until the lesion was excised surgically and examined by pathology. This case emphasizes the importance of early treatment or close monitoring for aberrant pancreas to avoid the potential cancerization and highlights that a protruding lesion in the stomach should prompt suspicion of a malignant pancreatic heterotopia.
