[Paraneoplastic syndromes in carcinoma of the kidney (author's transl)].

The authors present a group of patients with renal carcinoma in whom there were paraneoplastic signs such as fever, liver failure, hypertension and polycythemia. They noted, moreover, the most important clinical aspects, evaluating the incidence of these signs in relation to the course and diagnosis. They discuss also the frequency of presentation of each of these paraneoplastic manifestations, commenting on the various theories which have been suggested to explain them.
