RESUMENCARCINOMA RENAL QUE DEBUTA COMO CUADRO NEUROLÓGICO PARANEOPLÁSICO Introducción: Los procesos tumorales pueden de manera ocasional mostrar su primera manifestación con una sintomatología neurológica, no originada por metástasis, sino del denominado tipo paraneoplási-co, que puede aparecer incluso años antes de los síntomas habituales del tumor. Este tipo de manifestaciones iniciales pueden ser la clave del descubrimiento de una neoplasia oculta.Métodos: Presentamos el caso de un varón de 66 años afecto de un carcinoma renal, cuya manifestación inicial consistió únicamente en un cuadro neurológico progresivo de tipo cerebeloso paraneoplásico, aparecido 6 años antes de la primera sintomatología urológica.Conclusiones: La aparición de una sintomatología neurológica cerebelosa progresiva puede ser la única y primera manifestación de un carcinoma renal, incluso años antes de las primeras manifestaciones uroló-gicas. Debe sospecharse la existencia de una neoplasia oculta en los pacientes con esta sintomatología. ABSTRACTRENAL CELL CARCINOMA PRESENTING AS PARANEOPLASTIC NEUROLOGICAL DYSFUNCTION Introduction: Malignant tumors sometimes initiate as paraneoplastic syndromes even years before the most common symptoms appear. These first manifestations could be the key for the diagnosis of "occult" malignancy.Methods: We report the case of a 66 year old man with a renal cell carcinoma. The first symptom was a paraneoplastic cerebellar degeneration appeared 6 years before the first urologic manifestations.Conclusions: A progressive cerebellar syndrome could be the first manifestation of a renal cell carcinoma, even years before the first urologic symptoms. We must suspect an occult neoplasia in such patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
