Renal cell carcinoma (RCC) is the most common malignancy of the kidney. It is not commonly form tumor thrombus in the ureter or renal pelvis. A 29-year-old woman presented with asymptomatic gross hematuria. Contrast CT study revealed a tumor suspected to be a Transitional Cell Carcinoma (TCC). However, tumor thrombus was found in the renal pelvis and ureter. We performed Nephroureterectomy, bladder cuff excision, and lymph node dissection, and the tumor was diagnosed histopathologically as RCC. We report a very rare case of thrombus-like tumor of renal cell carcinoma mimicking transitional cell carcinoma of kidney.
肾细胞癌（RCC）是肾脏最常见的恶性肿瘤。它通常不会在输尿管或肾盂形成肿瘤血栓。一名29岁女性出现无症状肉眼血尿。增强CT检查发现一个疑似移行细胞癌（TCC）的肿瘤。然而，在肾盂和输尿管中发现了肿瘤血栓。我们进行了肾输尿管切除术、膀胱袖口切除术和淋巴结清扫术，病理组织学诊断该肿瘤为肾细胞癌。我们报告了一例非常罕见的肾细胞癌血栓样肿瘤，酷似肾移行细胞癌。
