title: [A Case of ACD-Associated RCC with Lymph Node Metastasis and Contralateral Renal Carcinoma after Nephrectomy].
abstract: A 59-year-old man who had undergone hemodialysis for 13 years was diagnosed with left renal cell carcinoma (RCC),cT1aN0M0,in 2010. He had a laparoscopic left nephrectomy,and the pathological diagnosis at that time was clear cell carcinoma,pT1a (multifocal). At 1 year after surgery,he was diagnosed with a left renal hilar lymph node metastasis and a new right RCC,cT1aN0M0. Consequently,he underwent a right nephrectomy and retroperitoneal lymph node dissection in 2012. Pathologic diagnosis by the current classification of the right renal tumor was acquired cystic disease-associated renal cell carcinoma (ACD-associated RCC),and that of the left hilar lymph node was metastatic RCC with sarcomatoid change. According to the revised classification the pathological diagnosis of the left renal tumor was ACD-associated RCC. There has been no evidence of recurrence or metastasis for 3 years after the second operation. The specific classification of dialysis-related renal tumors and their characteristics should be standard knowledge for urologists.
