INTRODUCTION
The presence of two different histologic types of renal cell carcinoma in the same kidney is rare in clinical practice. This report describes a patient with ipsilateral renal cell carcinomas, consisting of a clear cell renal cell carcinoma and a papillary type 1 renal cell carcinoma, who was successfully treated by robot-assisted partial nephrectomy.
CASE PRESENTATION
A 70-year man was referred to our hospital for the treatment of two right mid-pole renal tumors, measuring 51 mm and 31 mm in diameter. The two tumors, which differed in contrast enhancement on computed tomography, were removed simultaneously by robot-assisted partial nephrectomy. Histopathological and immunohistochemical findings confirmed that one tumor was a clear cell renal cell carcinoma, pT1a, and the other was a papillary type1 renal cell carcinoma, pT1b.
CONCLUSION
This report describes a rare patient presenting with two ipsilateral renal cell carcinomas differing in histology. Robot-assisted partial nephrectomy was the safe and effective nephron-sparing surgery, even in patients with complex double renal tumors.
引言
在同一侧肾脏中出现两种不同组织学类型的肾细胞癌在临床实践中较为罕见。本报告描述了一名患有同侧肾细胞癌的患者，其肿瘤包括透明细胞肾细胞癌和1型乳头状肾细胞癌，该患者通过机器人辅助部分肾切除术获得成功治疗。
病例介绍
一名70岁男性因右侧肾中极的两个肿瘤前来我院治疗，肿瘤直径分别为51毫米和31毫米。这两个在计算机断层扫描中对比增强不同的肿瘤，通过机器人辅助部分肾切除术同时切除。组织病理学和免疫组化结果证实，一个肿瘤为透明细胞肾细胞癌，pT1a期，另一个为1型乳头状肾细胞癌，pT1b期。
结论
本报告描述了一名罕见的患有两种不同组织学类型同侧肾细胞癌的患者。机器人辅助部分肾切除术是一种安全有效的保留肾单位手术，即使对于患有复杂双侧肾肿瘤的患者也是如此。
