Explain of Renal

70.Renal cell carcinoma, gross

This is a renal cell carcinoma arising in the lower pole of the kidney. It is fairly circumscribed. The cut surface demonstrates a variegated appearance with yellowish areas, white areas, brown areas, and hemorrhagic red areas. Though these neoplasms are usually slow-growing, they can often reach a considerable size before detection because there is a lot of room to enlarge in the retroperitoneum and there is another kidney to provide renal function. Thus, presenting symptoms and signs usually include flank pain, mass effect, and hematuria.
