We describe a case of pediatric acute lymphoblastic leukemia (ALL) with trisomy 5 as a sole cytogenetic abnormality. A comparison is made with the two cases of adult acute lymphoblastic leukemia with trisomy 5 in the literature. This rare cytogenetic abnormality may portend an especially poor prognosis in patients with ALL.
我们描述了一例小儿急性淋巴细胞白血病（ALL），其唯一的细胞遗传学异常为5号染色体三体。并与文献中两例成年急性淋巴细胞白血病伴5号染色体三体的病例进行了比较。这种罕见的细胞遗传学异常可能预示着ALL患者的预后特别差。
