Synchronous Renal Neoplasm: Clear Cell Renal Cell Carcinoma and Papillary Urothelial Carcinoma in the Same Kidney

Abstract

Abdominal computed tomography in a 64 year-old male presenting hematuria showed two malignant tumors in the left kidney, thus radical nephrectomy was realized. In histological preparations a clear cell renal cell carcinoma and a papillary urothelial carcinoma were identified occurring synchronously, which is a rare occurrence having only about 50 cases reported in the literature.
