Transient leukemia in phenotypically normal children is rare. A newborn child in whom fever and tachypnea developed at age 2 days had a white blood cell count of 20.1 x 10(9)/L and many abnormal blast cells. Chromosome analysis of spontaneously dividing cells from the blood showed these to have trisomy 21, and 80% of cells in the marrow were also trisomic. No trisomic cells were present in skin fibroblast cultures. At age 6 months, at which time the blood film appeared normal, trisomic cells were no longer present.
表型正常儿童的短暂性白血病很罕见。一名2日龄出现发热和呼吸急促的新生儿白细胞计数为20.1×10⁹/L,并有许多异常原始细胞。对血液中自发分裂细胞的染色体分析显示这些细胞存在21三体,骨髓中80%的细胞也为三体。皮肤成纤维细胞培养物中不存在三体细胞。6个月大时,此时血涂片看起来正常,三体细胞不再存在。
