Wilms tumor, also known as nephroblastoma, is the most common primary malignant renal tumor in children. It accounts for approximately 90% of all pediatric kidney cancers and roughly 6% of all childhood malignancies. Named after the German surgeon Max Wilms, who first described it in 1899, this embryonal tumor arises from abnormal renal development (metanephric blastema).
