Abstract
- Waldenstr's macroglobulinemia is a slowly progressing disease characterized by proliferation of small lymphocytes, plasmacytoid lymphocytes and plasma cells in the bone marrow with increased serum monoclonal IgM. Since 1944, only a few cases of Waldenstr's macroglobulinemia with pulmonary involvement have been described. We experienced a case of Waldenstr's macroglobulinemia with pulmonary involvement. The patient was 66-year-old male complaining dyspnea. His cytological finding of pleural fluid aspirates revealed many plasmacytoid lymphocytes. Serum electrophoresis showed the sharp M-peak in the gamma globulin region, which was identified as a IgM, kappa type by immunofixation. Bone marrow findings showed small lymphocytic and plasmacytoid lymphocytic infiltration.
