摘要 目的探讨肾嫌色细胞癌的临床病理学特征、免疫组化特点及诊断和鉴别诊断。方法对14例肾嫌色细胞癌患者进行临床病理学分析。结果本组14例患者,肿瘤直径3~12 cm,平均直径7 cm。肿物切面呈灰黄色或棕褐色,实性。镜下瘤细胞多呈实性巢索状排列,有灶性的管状或小梁状排列。癌细胞呈大圆形或多边形,胞膜较厚,界限清楚,透明的核周空晕明显。14例患者中,肉眼血尿6例,腰部胀痛5例,兼有3例,1例合并子宫颈鳞状细胞癌,1例有骨转移。免疫组化结果显示高分子量CK、EMA和CD117均阳性,7例CK7阳性;Vimentin均为阴性,Ki-67(+2%^+3%)。结论嫌色性肾细胞癌是来源于集合管上皮细胞的恶性肿瘤,预后较透明细胞癌好。
