Emergence of a new chronic myeloid neoplasm in the setting of a previous one, or their concomitant appearance seems to be a rare event, but plenty of cases have been reported. We describe the case of a patient with -V617F polycythemia vera, which looses clone and develops overt chronic myeloid leukemia after 6 years. Once treatment with tyrosine kinase inhibitors controls 1 clone, clone arises again. In this report, we review the literature and discuss the clonal relationship of this event in light of the new molecular data.
在前一种慢性髓系肿瘤的背景下出现新的慢性髓系肿瘤,或者它们同时出现似乎是一种罕见事件,但已有大量病例报道。我们描述了一名患有JAK2 V617F真性红细胞增多症的患者,该患者在6年后失去一个克隆并发展为明显的慢性髓系白血病。一旦用酪氨酸激酶抑制剂控制了一个克隆,另一个克隆又会出现。在本报告中,我们回顾了文献,并根据新的分子数据讨论了这一事件的克隆关系。
