MiTF/TFE • translocation RCCs may be inherently more aggressive in adults than in children; however, the relatively short follow-up periods currently available and the potential bias inherent in nonconsecutive case series and case reports preclude a definitive statement. • the current management for localized tumors is quite similar to conventional RCCs.
