IgG-kappa type multiple myeloma in alcoholic cirrhosis--a case report.

Transition from polyclonal to monoclonal gammopathy resulted in myeloma in the course of cirrhosis is rare but of interest. We treated such a case of multiple myeloma of IgG-kappa type associated with alcoholic cirrhosis. The case was a 72-year-old Japanese male patient who was admitted because of ascites and edema. Physical examination and laboratory findings including liver histology were compatible with alcoholic cirrhosis. Serum electrophoresis revealed monoclonal hypergammaglobulinemia of IgG-kappa. Bence Jones protein in urine was positive. Bone scintigraphy and roentgenography revealed small punched out lesions in the skull. A bone marrow clot section showed marked infiltration of atypical plasma cells. From these findings multiple myeloma associated with alcoholic cirrhosis was diagnosed. On the basis of a review of the reported cases, the possible relationship between monoclonal gammopathy and chronic liver diseases was discussed.
