Resumen

En los oligodendrogliomas la microscopía electrónica muestra células tumorales con características morfológicas propias de los oligodendrocitos. Un detalle característico es la observación de que las prolongaciones de las células del tumor muestran tendencia a formar laminillas concéntricas que se interpretan como un intento de formación de vainas de mielina.
