摘　　要：目的:探讨肾脏外周原始神经外胚叶肿瘤(pPNET)的临床和病理特征。方法:对1例肾脏原始神经外胚叶肿瘤临床表现、病理特征及免疫组化表型进行观察并文献复习。结果:患者男性,35岁,以肉眼血尿为首发症状,B超示左肾上极实性肿物。镜下可见核分裂相,肿瘤坏死明显,免疫组化CD99(+++)、NSE(+)、EMA(-),病变符合原始神经外胚叶肿瘤。结论:原始神经外胚叶肿瘤的诊断依赖病理特征及免疫表型,并需与其他小细胞恶性肿瘤进行鉴别。Objective：To explore the pathological and clinical characteristics of peripheral primitive neuroectoder mal tumor（PNET） of kidney.Methods：A case of PNETs of kidney was reported and the related literatures were reviewed,including the clinical symptoms,pathological characteristics,treatment and survial.Results：One case aged 35 male,the leader symptom was the grass hematuria,pole of left kidney mass,scope below,it was evident that nuclear disord aspect neoplasm necrosis;Tumor necrosis was obvious.Immunohisochemistry：CD99（＋＋＋）,NSE（＋）,EMA（-）,Pathological changes was PNET.Conclusion： The diagnose of PNET depends on pathological characteristics and expression of immunohisochemistry.
