El carcinoma de células de Merkel es un tumor cutáneo maligno poco frecuente, originado a partir de las células neuroendocrinas de la epidermis, denominadas células de Merkel. Presenta un pronóstico infausto cuando la enfermedad es diseminada. Dentro de las metástasis a distancia, la localización espinal es muy poco frecuente y no existe un consenso en cuanto a su manejo. Presentamos el segundo caso descrito en la literatura hasta el momento de afectación metastásica espinal por carcinoma de células de Merkel en paciente inmunodeprimido.
