title: Solitary ureteral metastases of renal cell carcinoma.
abstract: Metachronous presentation of metastatic renal cell carcinoma (RCC) to the ureter is extremely rare. We report a solitary metachronous metastatic RCC in the contralateral ureter 14 months after right radical nephrectomy for Fuhrman grade 2 pT3a clear cell disease after the patient re-presented with gross hematuria. The proximal left ureteral lesion was excised followed by ileal-ureteral interposition. Pathologic examination confirmed metastatic RCC. To date, only 51 cases of metastatic RCC to the ureter have been reported, with only 6 occurring metachronously in the contralateral ureter. Also, we report the presence of focal extramedullary hematopoiesis occurring within this metastatic lesion.
