Abstract
Renal cell carcinoma (RCC) of an allograft kidney is an extremely rare type of neoplasm and accounts for about 0.22-0.5% of all kidney recipients. Kidney recipients undergo routine check-up, including ultrasound examination of the graft. RCC is often asymptomatic and can be an incidental finding on routine examination. In this case study, we describe a patient who developed clear cell carcinoma 9 months after the kidney transplantation from a living related donor. Radiofrequency ablation was chosen as the treatment option, considering small size solitary lesion in renal allograft. Complete ablative response was achieved after one treatment. In 4-year follow up period patient did not show any new or recurrent tumor. Radiofrequency ablation is a good therapeutic option for kidney allograft carcinoma.
