There is an increasement on the incidence of tumours within the population of renal transplanted, from three to five times over general population. Related to urological tumours, it emphasizes an increase in the incidence of the renal Carcinoma, around 4,7% against 3% on general population. In this case, we present a 56 year old patient, who suffered a renal transplant 8 years ago. Incidentally, it is diagnosed a 3 cm mass at the back face of the transplanted kidney, suggestive of renal neoplasm. Given the characteristics of the mass, of the patient and because of the good graft function, we propose the non-sparing surgery of the transplanted kidney as treatment. The patient went back home 6 days after the surgery, with a Creatinine value of 106 µmol/L. The pathology of the piece was a papilar Carcinoma, type II, pT1aG3, free margins of tumour. The non-sparing techniques like the partial nephrectomy, the criotherapy and the radiofrequency ablation, can be useful and must be considered when it is tried to preserve the renal function, overall in case of bilateral tumours or solitary kidney, and in small and/or eccentric tumours. Renal neoplasms necessarily does not imply the loss of the graft and allows a similar handling to transplanted patient, applying conservative techniques in selected cases.
