色素性微囊肾嫌色细胞癌临床病理学观察

张 亚丽, 李 秀明

摘要

目的:探讨色素性微囊肾嫌色细胞癌的临床病理、诊断及鉴别诊断特征。方法:通过对一例色素性微囊肾嫌色细胞癌的临床、影像资料及组织学形态、免疫组化结果进行综合分析。结果:本例色素性微囊肾嫌色细胞癌大体境界尚清,切面呈灰棕色、质中,镜下瘤细胞排列主要呈微囊状、筛状结构,肿瘤间质稀少,并见较多钙化及色素沉着。免疫组化:E-caldherin、CD117、AE1/AE3、EMA、CAM5.2 均显示阳性,CK7 显示灶 。结论:色素性微囊肾嫌色细胞癌是一种特别少见的肿瘤,目前国内外报道皆少,该肿瘤具有相对良性的生物学行为,预后较好。
