Summary: | We report the case of a patient with alcoholic liver cirrhosis and generalized atherosclerosis who rapidly developed erythrocytosis. Concomitantly we documented a significative and progressive increase of serum Erythropoietin (Epo) and a small focus of hepatocellular carcinoma (HCC) never diagnosed before. Even in absence of immunohistochemical and/or biomolecular evidence of Epo production in the neoplastic tissue we think the hypothesis of the paraneoplastic syndrome may be the most likely both for the strict temporal relationship between the observation of the neoplastic lesion and the appearance of polycythemia and for the absence of all other known causes of erythrocytosis. Objection to this hypothesis: 1) ectopic production of Epo during HCC has been usually described in large neoplastic lesions 2) liver cirrhosis by itself may be accompanied by increased Epo levels 3) an intratumoral hypoxia with compensatory production of Epo may have occurred 4) generalized vasculopathy could have determined renal hypoxia with greater local production of Epo. |
