骨髓增生异常综合征（MDS ）是多能造血干细胞的恶性克隆性疾病，以骨髓无效造血，外周血一系或多系血细胞减少，骨髓一系或多系病态造血为特征，并具有向急性白血病转化等风险。MDS 可分为原发性及继发性。研究表明铅中毒可导致造血系统紊乱，该文报道1例因长期接触铅而引发继发性 MDS （s-MDS）的患者，其血铅、尿铅明显升高，全血细胞减少，伴有克隆性染色体异常。经予排铅治疗后，患者血常规恢复至接近正常水平，随访情况稳定。因此，临床上对于铅中毒且出现血常规异常的患者，应进一步行骨髓及染色体检查以排除 s-MDS 的可能。

Myelodysplastic syndrome (MDS)is malignant cloning disease of multipotential stem cells characterized by ineffective hematopoiesis of the bone marrow,peripheral single-or multi-lineage pancytopenia and single-or multi-lineage dyaplasia,and has a risk of evolving into acute leukemia.MDS can be divided into primary and secondary categories.It has been proven that lead poisoning can result in hematopoietic system dis-orders.In this paper,we reported one patient developing secondary MDS (s-MDS)after long-term exposure to lead.The patient presented with significantly elevated levels of lead in the blood and urine,pancytopenia and clonal chromosome abnormalities.After lead excretion,routine blood test revealed almost normal outcomes. The patient was physically stable during subsequent follow-up.Therefore,patients with lead poisoning and ab-normality of routine blood test should further receive bone marrow and chromosome examinations to exclude the possibility of s-MDS.
