This 38 y/o man presented with flank pain and hematuria. Imaging studies showed stone in the ureter with severe hydronephrosis. The patient underwent radical nephrectomy which revealed xanthogranulomatous pyelonephritis and multiple whitish lesion in the renal cortex and medulla ranging in size from 0.2 cm to 1.0 cm. This low-power scan of the slide reveals a 1.0 cm diameter papillary tumor arising in a cyst wall.
