肾细胞癌:切面色彩斑驳


肾脏下极的肾细胞癌,相当局限,切面色彩斑驳,有黄*色、白色、棕色区和出血的红色区。尽管肿块通常生长缓慢,但因为腹膜后有相当大的空间,所以在被发现前,肿瘤常常已长到相当大了。对侧的正常肾脏维持着肾脏功能。腰痛、肾区肿块和血尿是三个典型症状。
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.
