回顾分析了７例红白血病（急性髓系白血病Ｍ６）的形态学、免疫学、细胞遗传学特征。血象示二系或是三系减少，可见数量不等的有核红细胞。骨髓主要累及红系和粒系，但大部分患者有三系病态造血，有核红细胞ＰＡＳ染色呈阳性。白血病细胞主要表达血型糖蛋白、ＣＤ１３和ＣＤ３８。大部分患者有染色体核型异常，但均为随机非特异性改变。 The morphological, immunological and cytogenetic features of 7 cases of erythroleukemia (acute myeloid leukemia M6) were reviewed and analyzed. The blood showed a decrease in the second or third line, and a large number of nucleated red blood cells could be seen. The bone marrow mainly involved erythroid and granulocytic lines, but most patients had three series of pathological hematopoiesis, and nucleated red blood cells were positive for PAS staining. Leukemic cells mainly express blood group glycoproteins, CD13 and CD38. Most patients had karyotypic abnormalities, but all were random non-specific changes.
