Gross Description -- Right-sided Mass Involving Kidney and Liver


The specimen consists of a 3,127 gram gray-yellow to hemorrhagic mass, 30.0 x 18.0 x 14.0 cm. A 5.0 x 5.0 x 4.0 cm portion of exposed inferior pole of kidney has a smooth, tan capsular surface. At the superior aspect of the mass is a 6.0 x 5.0 x 3.0 cm portion of attached, cauterized liver tissue which on cut section shows underlying yellow-white to hemorrhagic tumor, which comes to within 0.2 cm of the surgical margin of resection. No normal adrenal gland is identified. A patent 6.0 cm segment of attached pink ureter has a smooth mucosal surface and no gross evidence of tumor. The coronally sectioned specimen reveals a 21.0 x 16.0 x 16.0 cm necrotic gray-yellow to hemorrhagic tumor surrounded partially by a 0.2-0.3 cm membranous capsule. The mass abuts the kidney, distorting the superior pole. However, no gross association between the tumor and kidney is identified. Capsule can be stripped from the kidney adjacent to the tumor. The renal cortex is 1.0 cm in thickness. The underlying medulla is tan and striated. The pelvis is pink and smooth. The hilar vessels are free of obstruction and/or tumor. Representative sections are submitted.
