摘要 目的探讨肾外肾母细胞瘤(extrarenal Wilms’tumor,EWT)的临床病理特征及诊断与鉴别诊断。方法对1例2岁幼儿左侧腹股沟区EWT合并隐睾行HE及免疫组化EnVision两步法染色,于光镜下观察组织形态学特征,并复习相关文献。结果镜下可见3种肿瘤成分,呈巢、片状排列的原始胚芽组织,由不同分化程度的肾小管结构组成的上皮成分以及肌纤维母细胞样间质成分,其中间质成分有向横纹肌分化区域。免疫表型:胚芽成分弥漫表达WT-1,上皮成分表达CKpan,间质横纹肌分化区域表达myogenin、desmin。结论 EWT十分罕见,好发于3岁以内婴幼儿,无明显临床体征,其确诊需依赖于病理学检查。
