Multiple myeloma (MM) is a common hematologic malignancy. Pieural effusion is a rare presenting feature of multiple myeloma which carries a poor prognosis. Few cases of multiple myeloma with pieural involvement have been reported in the medical literature. We report a patient with MM diagnosed by cytologic examination of pieural fluid. Our patient was a 64-year old man with multiple myeloma who was receiving chemotherapy. He had developed dry coughs and exertional dyspnea about a month prior to the admission. Radiographic examination showed left pieural effusion with mediastinal shift to the opposite side. Diagnostic thoracentesis ofpieurai fluid was performed for the patient. Pathologic examination ofpieurai fluid showed plasmocytes and plasmablast type mononuclear cells with atypical nuclei, consistent with the diagnosis of pieural effusion due to multiple myeloma. In view of multiple etiologies of pieural effusion in malignant diseases, rare etiologies should also be considered in order to treat the effusion appropriately.
