Carcinoma renal que debuta como cuadro neurológico paraneoplásico

RENAL 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 carcino- ma, even years before the first urologic symptoms. We must suspect an occult neoplasia in such patients.
