Abstract

采用高通量测序(NGS)、Sanger测序和荧光原位杂交(FISH)等方法检测福建省立医院于2013年7月至2019年8月诊断的3例儿童肾脏透明细胞肉瘤(CCSK)的BCOR和YWHAE-NUTM2B/E等基因的状态,并结合临床表现、组织学形态及免疫表型进行诊断和讨论。3例均为3~6岁男童,镜下见CCSK经典的组织学形态,但形态出现了变异。弥漫表达BCOR和cyclin D1蛋白,Sanger测序证实存在BCOR基因的内部串联重复性扩增,NGS及FISH检测证实不存在YWHAE-NUTM2B/E、BCOR-CCNB3等基因的重排。儿童肾脏CCSK具有特征的形态学表现,但因常出现形态变异而易误诊,分子遗传学检测为该肿瘤的确诊提供了重要依据。.
