RESUMO
La poliposis adenomatosa familiar (PAF) se caracteriza principalmente por el desarrollo de un gran número de pólipos en el tracto gastrointestinal y por un mayor riesgo de desarrollo de adenocarcinomas. A continuación presentamos el caso de una paciente diagnosticada de PAF y metástasis hepáticas, cuyo examen histológico reveló que eran secundarias a un tumor neuroendocrino. En la revisión bibliográfica sólo se han descrito hasta el momento 3 casos en los cuales ambas entidades coexisten. Actualmente no hay ninguna base genética que explique la coexistencia de estas 2 enfermedades cuyas prevalencias son muy bajas (AU)
Familial adenomatous polyposis (FAP) is mainly characterized by the development of a large number of polyps in the gastrointestinal tract and by the risk of developing adenocarcinomas. We present the case of a woman diagnosed with FAP and liver metastases. Histological analysis revealed both diseases to be secondary to a neuroendocrine tumor. To date, only three cases showing the simultaneous occurrence of these two entities have been published. Currently, there is no genetic basis to explain the coexistence of these two diseases, both of which have a very low prevalence (AU)
