本文报告5例易与早幼粒细胞白血病混淆的类早幼粒细胞白血病反应的粒细胞缺乏症（简称粒缺）。这一粒缺血象的临床表现与一般粒缺相同，但骨髓象突出异常为早幼粒增多，甚至高达30％以上，NEC高达50％以上，后期粒细胞很少，甚至消失。增多的早幼粒胞体增大，颗粒多而较粗大，但不密集，不见细颗粒，缺乏瘤状突起和异形性改变。 This article reports five cases of agranulocytosis (abbreviated as agranulocytosis) that are susceptible to promyelocytic leukemia. The clinical manifestations of this ischemic image are the same as those of normal granules, but the abnormality of bone marrow image is an increased number of early granules, even as high as more than 30%. NEC is as high as more than 50%, and granulocytes are few or even disappear in later stages. Increased promyelocytic bodies increase in size and are more coarse, but not dense, no fine particles, lack of knob-like protrusions and heteromorphic changes.
