血细胞形态学是诊断白血病的主要依据,但近年来,临床上常发现一些以贫血为主,或伴有外周血全血细胞减少的患者,而骨髓增生活跃,红系统增生,并有细胞形态异常改变,用常规抗贫血药物治疗不能奏效。对于这一类血细胞形态学多相性异常的骨髓病,国内外学者提出了一些新名称,如白血病前期,冒烟型白血病,低增生性白血病,低原始细胞性白血病等。 Blood cell morphology is the main basis for the diagnosis of leukemia, but in recent years, often found in clinical anemia or peripheral blood pancytopenia in patients with active bone marrow hyperplasia, red hyperplasia, and abnormal cell morphology changes , With conventional anti-anemia medication does not work. For this kind of abnormal morphology of blood cell morphology of bone marrow disease, scholars at home and abroad put forward some new names, such as pre-leukemia, fuming leukemia, hypo-proliferative leukemia, low-grade leukemia and so on.
