Wilms Tumor/Renal Blastema

• The tumor (T) is seen to the left which is the upper pole. It replaces the cortex and medulla in the area involved.
• The tumor does not distort the reniform shape of this kidney and is not massive in size. This Wilms tumor was discovered because the patient had Beckwith-Wiedemann syndrome.
• Note the presence of multiple nodular lesions in the remainder of the parenchyma which microscopically turned out to be benign renal blastema.
