title: [A case report of pleural involvement in primary macroglobulinemia].
abstract: A case of primary macroglobulinemia with pleural and gastric involvement was presented. A 48-year-old female was admitted with productive cough. On physical examination neither lymphoadenopathy nor hepatosplenomegaly were found. In addition, no bleeding tendency nor disturbance of the visual acuity were detected. Her chest roentgenogram showed a moderate amount of pleural effusion in the left pleural cavity without infiltration in the lung fields and no evidence of swollen hilar or mediastinal lymphnodes. A monoclonal M-band of to IgM-kappa type was observed in her serum and the pleural effusion. The diffuse ulcerative lesion in the gastric mucosa was detected by gastrofiberscopy. The lymphoid cells taken from the pleural effusion and the gastric mucosa stained positively with fluorescein-conjugated antiserum to u or the kappa chain. Pleural effusion and gastric infiltration of lymphoid cells improved remarkably following ACOP therapy.
