title: [A case of multiple myeloma associated with abnormal plasma cells and M-protein in pleural effusion].
abstract: A 77-year-old woman with hypertension was admitted to our hospital because of exertional dyspnea end peripheral edema. Chest X-ray showed cardiomegaly, pulmonary congestion and right pleural effusion. Hypertensive heart failure was diagnosed and treated, and right pleural effusion disappeared in 2 weeks. Abnormalities on laboratory data, i.e. anemia and increased ESR et al. continued after the improvement of heart failure. Serum IgG was elevated (2570 mg/dl), while IgA and IgM were decreased. Immunoelectrophoresis indicated the presence of monoclonal IgG-lambda in the serum. Bone marrow puncture revealed an increase in atypical plasma cells (38.4%). Multiple myeloma was diagnosed from these findings and treated with melphalan and prednisolone. But increases in atypical plasma cells (43.2%) and serum IgG (2573 mg/dl) continued. During treatment, right pleural effusion increased again. Thoracocentesis showed bloody effusion with numerous atypical plasma cells, and the presence of monoclonal IgG-lambda was indicated by immunoelectrophoresis. The patient died of renal and heart failure 2 months after the onset of malignant pleural effusion. Cytological examination and immunoelectrophoresis are necessary for pleural effusion in multiple myeloma.
