Abstract:
Two cases of renal oncocytoma are reviewed. A 67-year-old man and a 21-year-old man with a right renal mass were incidentally revealed by echography. Selective renal angiogram showed no spoke-wheel configuration of vessels in either case. Both cases were pathologically diagnosed as oncocytomas, constructed of large eosinophilic cells with granular cytoplasm and small regular nuclei. The electron micrograph showed cytoplasm packed abundantly with mitochondria. The two patients are in good condition 2.5 and 1.5 years after diagnosis.
