摘要 [目的]观察多房囊性肾细胞癌(MCRCC)免疫组化染色特征,并与透明细胞性肾细胞癌(CCRCC)进行比较。[方法]收集10例MCRCC和12例低核级的CCRCC,应用免疫组化Envision方法检查常用的肾肿瘤诊断标志物CK7、CD10、P504s、Vimentin、EMA、Cam5.2和PAX8在两者之间的表达情况并进行比较分析。[结果]MCRCC中,80.0%表达CK7,40.0%表达CD10,30.0%表达P504s,50.0%表达Vimentin,100.0%表达EMA、Cam5.2和PAX8。CCRCC中,16.7%表达CK7,91.7%表达CD10,25.0%表达P504s,58.3%表达Vimentin,100.0%表达EMA、Cam5.2和PAX8。MCRCC与CCRCC的免疫组化特征比较,CK7在前者的表达率明显较高(P<0.05),而CD10在前者的表达率明显较低(P<0.05),P504s、Vimentin、EMA、Cam5.2和PAX8等标志物在两者之间的表达率无明显差别(P>0.05)。[结论]MCRCC是一种组织学上独特的低级别肾肿瘤,免疫组化染色特征虽不同于CCRCC,但两者之间存在明显的重叠,组织形态学特征是鉴别诊断两者最重要的标准。
