肾碰撞性细胞癌1例报告并文献复习

Renal Collision Carcinoma:A Case Report with Review of the Literature

目的:报告1例肾盂移行细胞癌与肾实质细胞癌碰撞,探讨肾碰撞癌患者的临床、病理及影像学特点。材料与方法:回顾性分析1例肾撞癌患者的诊治过程并文献复习,进一步了解临床及影像学特征。结果:术中见右肾体积增大,肾上极可见灰白色质硬区,与周围组织无明显界限,较固定。大体切面皮质增厚,肾盂内充满灰白色肿物,浸润肾实质。病理诊断为肾碰撞癌,肾孟移行细胞癌与肾实质细胞癌碰撞。结论:肾碰撞场极为罕见,临床无特异性,影像学特征因病程进展而异,需借助病理,免疫组织化学等明确诊断,应与肾脏其它良恶性肿瘤鉴别。

Purpose：In order to explore the features of renal collisison cancer in clincal symptom,pathology,we reported on collision cancer case of transitional cell carcinoma and renal parenchyma cell carcinoma which was diagnosedin our department.Materials and Methods：Retrospective analysised on renal collisio cancer patient diagnosis and treatment process,and reviewed the related literature,so as to understand its clinical symptom and imageology features further more.Results：In the operation,we found the volume of right kidney increased and the superior part became gray and hard,fixed well,there was no obviously boundary with wurrounding tissues.General cross-section showed cortex thickened,the gray tumors full filled with pelvis,at the same time infiltrationg the real parenchyma.Pathological diagnosis was renal collision cancer：the collision between pelvis transitional cell carcinoma and renal parenchyma cell carcinoma.Conclusion：Renal collision cancer is extremely rare,there was no specificity features in the clinic,and its imageoloical characters according the different stage has different appearance.To clear diagnosis needs pahtology,immunohistochemistry and other methods,and must be idetified with other real tumors.
