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 localised disease.
Treatment is with nephrectomy, chemotherapy, and radiotherapy.
Wilms' tumour, 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' tumour is increased in certain congenital overgrowth syndromes, congenital non-overgrowth syndromes, and children with congenital urogenital anomalies. Long-term survival approaches 90% in localised disease.
