Renal cell carcinoma in the pediatric age group is a rare event, and its occurrence in the allograft (recipient) kidney is an uncommon event. There is no published review study in RCC of allograft kidneys in children and adolescents. In this study, we thoroughly searched English literature (PubMed, Google Scholar, and Google) in order to find all the reported allograft kidney RCCs in the patients who have been transplanted below the age of 18. There have been 12 reports of allograft RCC in this age group. Our result showed that the age of tumor detection according to donor age is lower comparing to non-allograft RCCs, and there is a significant male preponderance. RCC in the allografts is smaller and shows low nuclear grade and has a good prognosis. These findings emphasize the importance of routine allograft ultrasonography which results in earlier detection of RCC with smaller size and better outcome.
