摘要: 目的 了解伴CD14、CD7高表达的变异性急性早幼粒细胞白血病(APL)形态学改变情况及相关实验室检查结果,提高对APL的诊断正确率。方法 收集伴CD14、CD7高表达的APL患者的所有临床资料及实验室检查结果并进行分析。结果 APL患者细胞形态学与急性髓系白血病(AML)-M5有相似之处,核扭曲折叠比较明显,胞浆中颗粒细小,双核异常早幼粒细胞多见。免疫抗原:常规表达CD13、CD33、CD117和细胞质髓过氧化物酶(cMPO),高表达CD14、CD7。白血病基因定性筛查:PML-RARα融合基因为阳性,NPM-MLF1融合基因为可疑阳性。结论 APL易与AML-M2、AML-M5混肴。有些APL细胞形态较规则,似AML-M2,可通过PML-RARα融合基因阳性、细胞遗传学t(15;17)(q22;q21)易位排除AML-M2;有些APL细胞形态扭曲,折叠明显,胞质中颗粒细小,似AML-M5,可通过细胞化学染色(过氧化物酶强阳性、特异性酯酶阳性)排除AML-M5。综合临床及实验室检查结果可对APL作出诊断,伴有相关抗原表达以及变异性融合基因不影响对APL的诊断。

Abstract: Objective To investigate the morphological changes and related laboratory examination of variability acute promyelocytic leukemia(APL) with high expressions of CD14 and CD7,and to improve the accuracy of variability APL and reduce misdiagnosis. Methods All clinical data and the results of laboratory examination were collected. Results The morphology of this patient was similar to that of acute myelocytic leukemia(AML)-M5. The nuclear distortion was obvious. The cytoplasm had fine particles. The binuclear abnormal promyelocytic cells were common. Immunological antibodies routinely expressed CD13,CD33,CD117 and cytoplasm myeloperoxidase(cMPO),accompanied by high expressions of CD14 and CD7. Qualitative screening of leukemia genes showed that PML-RARα fusion gene was positive,but NPM-MLF1 fusion gene was suspected positive. Conclusions APL is easy to mix with AML-M2 and AML-M5. Its morphology is similar to AML-M2. AML-M2 can be excluded by PML-RARαfusion gene-positive,cytogenetic t(15;17)(q22;q21) translocation. Some cell morphology is distorted and folded,and the cytoplasm has fine particles,which is similar to AML-M5. AML-M5 can be excluded by histochemical staining for peroxidase-positive and specific lipase-positive. It should synthesize clinical and laboratory examination to diagnose APL,and the diagnosis of APL is not affected by the expression of related antigens and the mutated fusion gene.
