目的:讨论儿童慢性再生障碍性贫血(CAA)和骨髓增生异常综合征(MDS)形态学特点与诊断的关系。方法:对9例CAA、10例MDS做血象、骨髓象比较分析。结果:MDS组知系病态造血明显,粒、红系原+早幼细胞比例明显高于MDS组,骨髓小粒中巨核细胞数CAA组明显少于MDS组,同时骨髓小粒中组织嗜碱组织均多见,结论:血象骨髓象检查对儿童CAA和MDS的诊断和鉴别诊断有重要参考价值。
Objective: To discuss the relationship between morphological features and diagnosis of children with chronic aplastic anemia (CAA) and myelodysplastic syndrome (MDS). Methods: 9 cases of CAA, 10 cases of MDS to do blood, bone marrow as a comparative analysis. Results: The morbid hematopoiesis was obvious in MDS group, the ratio of granule and erythroid progenitor cells was significantly higher than that in MDS group, the number of megakaryocytes in bone marrow granule was significantly less than that in MDS group, meanwhile there were more basophils in bone marrow granule See, Conclusion: Bone marrow like blood test for the diagnosis and differential diagnosis of CAA and MDS have important reference value.
