RESUMEN
La leucemia congénita constituye una entidad rara que se diagnostica entre el momento del nacimiento y los primeros 30 días de vida. Menos del 1 % de las leucemias de la infancia se diagnostican en el neonato. Se caracteriza por la presencia en un recién nacido, de hepatomegalia, esplenomegalia y lesiones hemorrágicas o infiltrativas en piel. El hemograma completo, el examen de la lámina de la sangre periférica, el aspirado de médula ósea, junto con el inmunofenotipaje y los estudios de biología molecular confirmarán el diagnóstico. El trastorno mieloproliferativo transitorio y las infecciones congénitas constituyen los principales diagnósticos diferenciales. El pronóstico de la enfermedad es sombrío. El tratamiento está basado en regímenes de poliquimioterapia intensiva y el trasplante de progenitores hematopoyéticos constituye una opción terapéutica en un grupo de pacientes.
