Eighty-two (78.8%), 108 (94.2%) and 57 (46.3%) were respectively low grade (Fuhrman 1-2), T1 stage and papillary carcinoma subtype. Ninety-six (78%) tumors were diagnosed by routine surveillance imaging. Mean time lapse between transplantation and RCC diagnosis was 143 months. Patients were treated by transplantectomy

They were small, low grade with more papilla subtype than in general population. Conservative treatment is feasible and safe, it should be preferred when possible to avoid return to dialysis. Annual screening by imaging seems essential. KEY WORDS : Kidney Transplantation ; Kidney cancer ; Ablative therapy ; Nephrectomy ; Nephron sparing surgery
