Case 108

Surgical Pathology Case


  A 56-year-old female. Right renal cell tumor.



The specimen consists of a right kidney with surrounding perinephric fat (420 grams, 15.0 x 7.5 x 5.5 cm), attached ureter (7 cm in length), and renal vein and artery. Bivalving the specimen reveals a well circumscribed yellow tumor (8.0 x 7.0 x 3.5 cm) at the inferior pole. The tumor is confined to the kidney and does not invade into perirenal fat. The tumor is clearly seen invading the renal vein, a tumor plug is seen in the renal vein at the hilum (2.5 x 2.0 x 1.0 cm). The renal vein, artery, and ureter at the resection margin are free of tumor. The remaining renal parenchyma is unremarkable, the cortex measuring 0.7 cm in thickness. Medullary striations are prominent.
