Resumen
El carcinoma de células de Merkel es un tumor raro neuroendocrino, altamente agresivo con altas tasas de mortalidad asociadas a sus metástasis a distancia. Es más frecuente en pacientes inmunosupresos, edad avanzada y exposición a luz ultravioleta. La mayoría de asocian con Poliomavirus sin embargo existen casos sin presencia viral. Se recomienda la resección quirúrgica con márgenes extensos cuando se encuentra localizado y en casos seleccionados la biopsia de ganglio centinela. Es una neoplasia quimiosensible y radiosensible. Existen avances terapéuticos inmunológicos para casos avanzados.
