Renal cell carcinoma (RCC) accounts for about 85% of all renal neoplasms, 60% of which are diagnosed incidentally. Most are unilateral, but bilateral tumors, synchronous or asynchronous, have been found in 2%–4% of reported sporadic cases. The occurrence of synchronous bilateral renal neoplasms with different histology in the same individual is very rare. We report one such case in a 45-year-old male patient, who was successfully managed by performing bilateral partial nephrectomy in two sittings. The histopathological examination revealed different histology on each side. Both preservations of renal parenchyma and tumor eradication should be considered in bilateral synchronous sporadic RCC before formulating a therapeutic regime. Management by nephron-sparing surgery approach performed in a staged manner offers adequate cancer-specific survival while ensuring good renal function.
