“…The term choristoma is derived from the Greek root “choristos,” meaning separated and also means mass or tumor. The term is synonymous with heterotopia and ectopia, which are defined as the proliferation of normal cells in an abnormal location [ 1 ] and an ectopic, histologically normal mature tissue. [ 18 ] Hamartoma is defined as a lesion containing mature and well-differentiated ectoderm and mesoderm derivatives that appear in abnormal locations [ 2 , 19 ] ; usually, 1 component dominates.…”

“…Choristoma is a tumor-like structure composed of normal tissue located at an abnormal site. [ 1 ] While it can occur anywhere in the body, it is more frequently observed in the head and neck region, especially in the pituitary gland [ 2 ] and oral cavity. [ 3 ] Intraspinal choristomas are rare and, to the best of our knowledge, only 2 cases have been reported.…”

“…Los coristomas son un hallazgo común en el tracto gastrointestinal, y se encuentran de manera accidental durante exámenes de imágenes como tomografías e invasivos como endoscopia. 9 El tejido heterotópico puede ocurrir en cualquier ubicación del recorrido gastrointestinal, siendo los sitios más frecuentes estomago e intestino delgado. 1 El páncreas aberrante o heterotópico, es una masa aislada de tejido pancreático, separada completamente del órgano principal, donde se produce embriogénesis propia, pero se desconoce su modo de desarrollo.…”

“…Sabemos de la posibilidad de degeneración maligna que este tejido ectópico puede sufrir y es por ello que de forma preventiva se sugiere controlar al paciente periódicamente después del procedimiento quirúrgico, para detectar eventuales recidivas, aunque es raro y poco reportado. 8,9…”

“…Pancreatic heterotopia/ectopia (PE), defined as the presence of pancreatic tissue outside its physiological location and without vascular or other anatomical connections to the native pancreas, is a frequent condition, largely occurring within the gastrointestinal tract 64 . It is widely accepted that most ectopic pancreatic rests, with the exception of pancreatic metaplasia in chronic atrophic gastritis, represent congenital heterotopias, rather than metaplasias 64 .…”
