ABSTRACT

We report three cases of pancreatic heterotopia incidentally found (one in autopsy and two in surgical pieces) with a brief review of the literature.
Cases: 1. A fifty-three-year-old woman who died of bronchopneumonia. During post-mortem examination, a nodule (hystologically formed by multiple ducts lined by columnar epithelium and broad disarranged smooth muscle fibers) was found at the level of jejune.
2. 5-year, 11-month-old male with diagnosis of choledochal cyst. In the resected specimen, one of the mural slices showed a tissue stripe that under light-microscope examination corresponded to normal pancreatic tissue.
3. 6-year, 10-month-old female diagnosed with Byler syndrome who was recipient of liver transplant. Slices taken from the hilum in the resected specimen revealed multiple clusters of pancreatic acini and ducts without evidence of endocrine islets.
Conclusion: Pancreatic heterotopia is an uncommon finding, which may be found at any level of the gastrointestinal tract, and even outside it. Histopathologic studies allow to distinguish this disorder from other lesions. Despite its commonly benign and asymptomatic behaviour, it may sometimes produce obstruction, hemorrhage, inflammation or neoplasms.
