ABSTRACT
Los quistes intestinales (tailgut cyst), o hamartomas quísticos retrorrectales, son lesiones benignas raras que se incluyen en la categoría de lesiones quísticas del desarrollo. Aunque existen varias hipótesis con respecto a su desarrollo, actualmente sigue sin conocerse con certeza su origen. Se localizan principalmente en el espacio presacro (retrorrectal) y afectan fundamentalmente a mujeres de edad media (40-60 años).Teniendo en cuenta su localización y características histológicas, los principales diagnósticos diferenciales incluyen quistes epidermoides, quistes de duplicación y teratomas.La transformación maligna de estas lesiones es rara, la mayoría en forma de adenocarcinoma y tumores neuroendocrinos.Nosotros presentamos un caso de un quiste intestinal asociado a tumor neuroendocrino bien diferenciado (G1) en una mujer de 63 años.(AU)
