RESUMEN

Esta revisión proporciona los conceptos más actuales relacionados con la patogénesis y diagnóstico histopatológico de los tumores neuroendocrinos del aparato gastrointestinal y del páncreas. Los tumores del sistema difuso de células neuroendocrinas comprenden un grupo de neoplasias con morfología similar, pero difieren en sus características biológicas, pronósticas y aspectos moleculares. En el compartimiento gastroenteropancreático, se clasifican como tumores neuroendocrinos bien diferenciados, carcinomas de bajo grado o carcinomas poco diferenciados. Los tumores endocrinos pancreáticos son relativamente raros, representan 1 a 2% de todas las neoplasias de este órgano y la mayor parte son bien diferenciados.
