Treated Wilms tumor

Treated Wilms tumor •The tumor at the time of discovery was too massive to surgically remove. The patient was treated with chemotherapy first. The tumor reduced in size and was removed. •Note the fibrous rim (arrow) that demarcates the tumor from the uninvolved kidney. •The gross features suggest that the tumor originated from the peripheral renal parenchyma.
