INTRODUCTION
Renal tumors are often associated with renal cysts. Meanwhile, in some cases there are challenging issues of how to diagnose renal cystic tumors and to decide surgical procedures.
CASE PRESENTATION
A 75-year-old man was referred to our department for a 21-mm tumor by his left kidney. Contrast-enhanced computed tomography showed an intense contrast uptake the tumor, which was adjacent to a 64-mm unilocular renal cyst with no contrasting effects. It was clinically diagnosed as renal cell carcinoma, stage T1aN0M0, and treated with robot-assisted partial nephrectomy, for both the solid tumor and the adjacent cyst. Pathological findings revealed a tumor cell clump within the cyst wall, concurrent with the renal cell carcinoma. The patient has remained free of disease at 1 year after surgery.
CONCLUSION
A partial nephrectomy that includes the entire cyst wall should be considered for renal tumor associated with unilocular renal cyst.
引言
肾肿瘤常与肾囊肿相关。同时，在某些情况下，如何诊断肾囊性肿瘤以及决定手术方式存在挑战性问题。
病例介绍
一名75岁男性因左肾有一个21毫米的肿瘤被转诊至我科。增强计算机断层扫描显示肿瘤有强烈的造影剂摄取，该肿瘤毗邻一个64毫米的单房肾囊肿，无造影剂增强效应。临床诊断为肾细胞癌，T1aN0M0期，对实性肿瘤及相邻囊肿行机器人辅助部分肾切除术。病理结果显示囊肿壁内有肿瘤细胞团，与肾细胞癌并存。患者术后1年无疾病复发。
结论
对于与单房肾囊肿相关的肾肿瘤，应考虑行包括整个囊肿壁的部分肾切除术。
