Synchronous Ipsilateral Renal Cell and Transitional Cell Carcinomas: A Case Report
摘要
The simultaneous occurrence of ipsilateral transitional cell carcinoma (TCC) and renal cell carcinoma (RCC) is rare. There are 47 such cases in the published literature worldwide. We report on a 78-year-old man with synchronous ipsilateral renal adenocarcinoma and renal pelvic TCC. He was referred to our department due to asymptomatic gross hematuria for 6 months. A computed tomographic scan and renal angiography revealed a 6-cm renal mass, which was exophytic, heterogeneous, and hypervascular in the lower pole of the right kidney. Retrograde pyelography demonstrated a filling defect in the upper calyces of the right kidney. Under the impression of TCC by urine cytology and suspicion of RCC, a right nephroureterectomy and bladder cuff resection were performed. Pathological diagnosis revealed a grade 2 TCC and clear-cell RCC.
