Renal cell carcinoma (carcinoma of kidney) also known as renal cell carcinoma originated in the renal tubular epithelial cells, can occur at any part of the renal parenchyma, but the above lower levels for the more common, a few invading the whole kidney; the left and right kidney disease equal opportunities , bilateral lesions accounted for 1% ~ 2%.
Giant Inspection: Tumor appearance of irregular round or oval-shaped mass, there is a layer of fiber pack a loss; rich blood supply, vascular engorgement, there is congestion and bleeding area. The colors and the number of tumor blood vessels, cancer cells within the lipid content and hemorrhage, necrosis and other factors, generally speaking, the growth of an active area is white, transparent cells, yellow, granule cells, or differentiated cells were white. Dark red or red lesions were stale or fresh bleeding areas, often cystic degeneration, central necrosis, hematoma or irregular calcification.
Microscopic examination: the main types of cancer clear cell carcinoma, granular cell carcinoma and undifferentiated carcinoma, etc., of which the clear cell carcinoma is common. Clear cell carcinoma of the large volume, edge clear, showing polygonal, nuclear small and uniform, staining deep; cell mass Duocheng transparent color. Cells, often arranged in sheets, papillary or tubular. Granular cells were round, polygonal or irregular shape, dark; cytoplasm filled with small particles, less cytoplasm; nuclear slightly deep dyeing. There is also a higher degree of malignancy of the kidney, the cells were spindle-shaped, nuclear large or mixed large and small, have more mitotic figures, showed sarcoma-like structure, known as undifferentiated carcinoma.
