In contrast to anaemia, polycythaemia is a distinctly uncommon finding in patients with multiple myeloma. We describe the presence of otherwise unexplained polycythaemia in a 57-year-old Caucasian man who was found to have IgG κ multiple myeloma. After treatment of myeloma, the polycythaemia resolved. We reviewed previous reports of polycythaemia associated with multiple myeloma and discuss potential pathophysiological mechanisms that link these 2 conditions.
与贫血相反,真性红细胞增多症在多发性骨髓瘤患者中是一种明显不常见的表现。我们描述了一名57岁白种男性患者存在无法解释的真性红细胞增多症,该患者被诊断为IgG κ型多发性骨髓瘤。骨髓瘤治疗后,真性红细胞增多症得到缓解。我们回顾了既往关于多发性骨髓瘤相关真性红细胞增多症的报道,并讨论了将这两种情况联系起来的潜在病理生理机制。
