We report 2 cases of de novo renal cell carcinoma (RCC) in renal grafts after transplantation. Both patients underwent nephron sparing surgery (NSS) 211 and 167 months after transplantation, revealing papillary RCC with a tumour size >4 cm (pT1a). Within a follow-up of 25 and 32 months after NSS, a stable renal function without indication for dialysis was present. No recurrence of RCC in both cases was reported within the yearly routine examinations. NSS in kidney allografts is a safe procedure with preservation of renal function.
