目的提高对家族性白血病的了解及认识。方法对1对母女同时患急性单核细胞性白血病(M5b)的临床资料、细胞形态学、流式细胞仪免疫分型结果进行分析,并结合文献进行复习。结果该对母女几乎同时期发病,且急性白血病细胞亚型完全一致,经细胞形态学和流式细胞仪免疫分型证实诊断。结论家族性白血病国内外均见少量文献报道,母女同时患同一种类型急性白血病的病例鲜见报道。 Objective To improve understanding and understanding of familial leukemia. Methods The clinical data, cell morphology and flow cytometry immunophenotyping results of 1 female and single female with concurrent acute monocytic leukemia (M5b) were analyzed and reviewed. Results The mother and daughter were almost the same period of onset, and acute leukemia cell subtype exactly the same, confirmed by cytomorphology and flow cytometry immunodiagnosis. Conclusion There are a few reports of familial leukemia both at home and abroad. There are seldom reported cases of mother and daughter suffering from the same type of acute leukemia at the same time.
