ABSTRACT
The development of malignant tumors is a more frequent finding in lupus patients than the general population. However, the incidence of multiple myeloma associated with systemic lupus erythematosus (SLE) is a rare manifestation. SLE is an autoimmune disease characterized by B cell hyperactivity, formation of autoantibodies, and multi-clonal hypergammaglobulinemia. Serum immunoglobulin increases, with a specific increase in IgG, which is due to an increase in autoantibody formation related to extrinsic and intrinsic antigens. We report on a patient with SLE combined with IgG, lambda type nonsecretory multiple myeloma, which was diagnosed with refractory anemia and hypergammaglobulinemia.

Thrombocytopenia is frequently seen in patients with multiple myeloma when most often the etiology is either chemotherapy induced marrow suppression or bone marrow replacement by myeloma cells. But immune thrombocytopenia has only rarely been documented in patients with multiple myeloma. Also ascites caused by peritoneal infiltration with myeloma cell rarely develops in patients with multiple myeloma. We report a patient with nonsecretory multiple myeloma associated with immune thrombocytopenia and complicated by malignant ascites and periumbilical nodules.
