RR CC was named for its morphologic resemblance to pediatric malignant rhabdoid tumor (MRT) of the kidney, which is a highly aggressive tumor characterized by cells that resemble rhabdomyoblasts and by genetic alterations involving chromosome 22, particularly the hSNF5/INI1 gene on 22q11.2. [13, 14] MRT usually arises in children younger than 3 years, and the occasional cases previously reported as adult MRT are now considered more likely to be RRCC in which rhabdoid components have overgrown the original histologic tumor type.
