Pancreatic Endocrine Heterotopia Involving Meckel’s Diverticulum: A Potential Mimic of Neuroendocrine Tumor

Pancreatic heterotopia most commonly occurs in the upper gastrointestinal tract, but can occur in other sites, including Meckel’s diverticulum. When multiple histologic elements of the pancreatic tissue (acini, ducts, and endocrine cells) are present, the diagnosis is typically straightforward. In this article, we report a rare case of pure endocrine pancreatic heterotopia involving a Meckel’s diverticulum, a potential mimic of a...
