Most common renal malignancy in children.
Presents as a unilateral, painless, abdominal/flank mass; rarely presents bilaterally.
Metastatic disease occurs in <10% of patients and needs to be carefully excluded using ultrasound and CT/MRI.
Long-term survival approaches 90% in localized disease.
Treatment is with nephrectomy, chemotherapy, and radiation therapy.
Wilms tumor, or nephroblastoma, is the most common form of renal malignancy in childhood. It usually occurs in the first 2 to 5 years of life. Approximately 500 children and adolescents <20 years of age are diagnosed each year in the US. The risk for developing Wilms tumor is increased in certain congenital overgrowth syndromes, congenital nonovergrowth syndromes, and children with congenital urogenital anomalies. Long-term survival approaches 90% in localized disease.
