Three patients had the rare occurrence of multiple myeloma coexisting with chronic lymphocytic leukemia or lymphosarcoma. It is not possible at present to resolve the question as to whether these two diseases represent part of the spectrum of a single B-cell disease or wether multiple myeloma and lymphoproliferative disorders are two separate entities, which may rarely occur by coincidence in the same patient.
三名患者出现了罕见的多发性骨髓瘤与慢性淋巴细胞白血病或淋巴肉瘤共存的情况。目前尚无法解决这两种疾病是代表单一B细胞疾病谱的一部分，还是多发性骨髓瘤和淋巴增殖性疾病是两个独立的实体，只是在同一患者中很少偶然同时出现的问题。
