Multiple myeloma (MM) is typically characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin. Pleural effusion in MM is uncommon and usually caused by heart failure, pulmonary embolus, and nephrotic syndrome [. 1978;138(5):727-30; . 1994;105(2):622-4]. Here, we report a case of myelomatous pleural effusion as part of the initial presentation of MM in a patient with the IgG-lambda subtype, which is extremely uncommon.
多发性骨髓瘤（MM）的典型特征是产生单克隆免疫球蛋白的浆细胞发生肿瘤性增殖。MM患者出现胸腔积液并不常见，通常由心力衰竭、肺栓塞和肾病综合征引起[。1978年；138(5):727 - 30；。1994年；105(2):622 - 4]。在此，我们报告一例IgG-λ亚型MM患者，其最初表现为骨髓瘤性胸腔积液，这种情况极为罕见。
