[Relation between monoclonal gammopathy and hepatobiliary disease].

Eleven cases of monoclonal gammopathy associated with chronic hepato-biliary diseases are reported. The gammopathy was benign and the majority of hepato-biliary diseases consisted of cirrhosis complicated or not by hepatocellular carcinoma. The small number of cases reported and the absence of distinctive clinical, biochemical and evolutive features of the gammopathy and hepato-biliary disease suggest that the association was fortuitous.
