[Polycythemia as the first and only manifestation of renal adenocarcinoma].
We report on a 40-year-old patient with adenocarcinoma of the right kidney whose first and only manifestation was the erythrocytosis that had been detected on routine analytical work up. The diagnostic methods (US, IVP, CT, aspiration biopsy cytology and renal arteriography) and treatment (right nephrectomy via extended thoracophrenolaparotomy incision at the level of the ninth rib) are briefly described. The polycythemia remitted following nephrectomy. The etiopathogenesis and hypotheses that have been put forward relative to polycythemia in renal adenocarcinoma are briefly discussed. Renal tumor, particularly renal adenocarcinoma, should be suspected in the presence of polycythemia of unknown origin. Persistent or recurrent polycythemia should prompt us to suspect incomplete tumor excision or metastasis. Surgical risks (embolism, hemorrhage, etc.) may be reduced if hematocrit levels are brought down to within normal levels by bleeding.
