Abstract

Co-existence of three M-components in the serum or urine is rare. A case of non-Hodgkin's lymphoma was associated with three M-components. A 64-year-old woman was referred to our hospital because of M-proteinemia in June, 1989. On admission, serum electrophoresis on cellulose acetate membrane disclosed a triple M-peak. Immunoelectrophoresis showed M-bows for anti-IgG, anti-IgA, anti-IgM and anti-kappa simultaneously. In the urine, kappa type only Bence Jones protein was found. Scanning computed tomography revealed bulky masses in the lower abdomen, and the tumor masses were removed and diagnosed as non-Hodgkin's lymphoma. Immunohistochemical staining with antibodies to each immunoglobulins revealed the cells producing single M-component of each isotype of immunoglobulins. Although surgical removal of tumor caused a marked decrease in M-component especially IgA kappa, consistent presence of plasmacytoid lymphocyte was observed in peripheral blood. Combination therapy with melphalan and procarbazine resulted in disappearance of IgG kappa and IgA kappa from the serum. In January 1990, she achieved partial remission and was discharged. The patient has remained in remission for 16 months.
