El coristoma pancreático, o páncreas heterotópico, es una condición rara en gastroenterología. Esta entidad consiste en el hallazgo de tejido pancreático aberrante, en alguna zona del tracto gastrointestinal, sin continuidad vascular o anatómica con el páncreas normal, es poco reportado y presenta sintomatología variable.

Presentamos el caso de un individuo de 46 años con dolor abdominal a quien se le encontró mediante exámenes invasivos un divertículo duodenal, el cual al examen histopatológico e inmunohistoquímico mostró un coristoma pancreático.

Pancreatic choristoma, also called heterotopic pancreas is a rare condition in gastroenterology. This entity consists of the presence of aberrant pancreatic tissue in some other area of the gastrointestinal tract without vascular or anatomical continuity with the normal pancreas; it has been seldomly reported and it could exhibit variable symptomathology.
