What is the difference between Wilms tumor and renal cell carcinoma?

WTs are widely regarded as embryonal tumors, which stem from meta-nephrogenic blastema. A renal cell carcinoma (RCC) is a rare malignancy in children. Unlike WTs, most pediatric cases of RCCs are diagnosed in the second decade of life, and the possibility of morbidity increases with age.
