A case of multiple myeloma with various kinds of paraproteins.

A case of multiple myeloma with various kinds of paraproteins is described in this report. IgG 3-λ type monoclonal protein, γ3-heavy chain and Bence Jones protein-λ were detected in the serum of a 60-year-old male patient. Also, γ3-heavy chain and Bence Jones protein-λ were detected in the urine. The final diagnosis of this case seems to be multiple myeloma with whole molecule and its fragments of monoclonal immunoglobulin G.
