Neuroblastoma-associated renal cell carcinoma (RCC) is a very rare subtype of renal neoplasia and only a handful of cases have been reported. Here we present a 15-year-old boy with metastatic RCC with a previous history of advanced stage neuroblastoma and germline mutation in the TP53 tumor suppressor gene. The probability of the RCC and indeed, the neuroblastoma itself being related to a cancer predisposition syndrome rather than a therapy induced second malignancy, is discussed.
