Abstract
El Melanoma Maligno es una de las neoplasias más agresivas, siendo responsable del 90% de las muertes por cáncer de piel; Su incidencia fue incrementándose durante las últimas décadas a nivel mundial. La progresión de la enfermedad puede presentarse en forma de recurrencia local, por diseminación linfática hacia los ganglios regionales, o por metástasis hematógena a sitios distantes: piel, órganos y hueso entre otros. Las metástasis regionales y a distancia, se presentan aproximadamente en 10% de los pacientes con melanoma, al momento del diagnóstico, conllevando peor pronóstico. La supervivencia a 5 y 10 años en pacientes con metástasis a distancia es de 12%-15% y 8%, respectivamente. Se presenta el caso de un paciente que rechaza tratamiento inicial de ablación de lesión primaria, presentándose múltiples metástasis y desenlace fatal.
The malignant melanoma is one of the most aggressive neoplasias, being responsible for 90% of the deaths due to skin cancer; its incidence was increasing during the last decades worldwide. The progression of the disease can occur in the form of local recurrence, by lymphatic dissemination to the regional ganglia, or by hematogenous metastasis to distant sites: skin, organs and bone among others. Regional and distant metastasis occurs in approximately 10% of patients with melanoma at the time of diagnosis, leading to a worse prognosis. The 5-year and 10-year survival in patients with distant metastasis is 12% - 15% and 8%, respectively. The case of a patient who refuses initial treatment of primary lesion is presented, presenting multiple metastasis and fatal outcome.
