lobulated tan-white mass
This small kidney from a 4 year old child contains a lobulated tan-white mass. This is Wilms tumor of the kidney. Many are now known to be associated with genetic defects on chromosome 11. The children with Wilms tumor usually present with abdominal enlargement from the mass effect. Nowadays, treatment gives a better than 90% 5 year survival
