RESUMEN
Los Síndromes Neurológicos Paraneoplásicos (SxNP) del sistema Nervioso Periférico (SxNP–SNP) incluyen trastornos de las raíces, plexos, nervios periféricos, unión neuromuscular y músculo. Los SxNP del Sistema Nervioso Autónomo (SxNP–SA) incluyen trastornos de inervación simpática o parasimpática, en especial del tubo digestivo y sistema cardiovascular, todas asociadas con neoplasia y/o anticuerpos antionconeuronales. Los SxNP SNP más comunes son la Neuronopatía Sensitiva Paraneoplásica (NSP) y el Síndrome Miasteniforme de Lambert-Eaton (SLE). La NSP precede hasta en 50-74% de las veces a una panencefalomielitis y frecuentemente tiene anticuerpos anti-Hu asociados con carcinoma de células pequeñas de pulmón. Por otra parte, desde su descripción el SLE se considera como uno de los SxNP más clásicos. Se caracteriza por falla presináptica producida por anticuerpos anti canales de calcio voltaje dependiente tipo V/Q necesarios para la liberación de acetilcolina, y se asocia a neoplasia en 40-60%. En esta revisión se describen en detalle los SxNPx del sistema nervioso periférico y autónomo.
