Alpha-1-antitrypsin deficiency resulting in a hitherto unseen presentation of hepatocellular carcinoma: Polycythemia but with normal alpha fetoprotein

Polycythemia is a known paraneopastic manifestation of hepatoma, but only in the presence of alpha-fetopro (AFP). We present a case of polycythemia in the absence of AFP, and suggest concurrent alpha-1-antitrypsin deficiency as the cause for breaking this rule. We also suggest a reason for the apparent constant conjunction between polycythemia and AFP in hepatoma.
