ABSTRACT
El neurocitoma o tumor epitelial disembrioplásico (TND) es un tumor infrecuente del sistema nervioso central (SNC) clasificado Grado I, según la OMS, y las series que aparecen en la literatura médica informan de pocos casos. Por considerarse una entidad poco frecuente y por haber asistido en un corto período a 2 pacientes adolescentes uno con recidiva de tumor cerebral que fue reintervenido y donde el diagnóstico patológico inicial se correspondía con un astrocitoma de bajo grado y la otra, llevada a sala de operaciones con el diagnóstico de astrocitoma de alto grado, y donde después de estudios de inmunohistoquímica el diagnóstico final fue de tumor neuroepitelial disembrioplásico extraventricular. Se indicó tratamiento con radiaciones ionizantes. Se decidió revisar la literatura y presentar estos 2 casos
The Neurocytoma or dysembryoplasia epithelial tumor (DET) is an infrequent tumor of the central nervous system (CNS) classified as Degree I according to the WHO and the series appearing in the medical literature report not much cases.
