Stains / Test Description
In normal kidney, renal cell carcinoma (RCC1, gp200) is localized along the brush border of the proximal tubule. In other normal tissues, RCC is also localized along the luminal surfaces of breast lobules and ducts, the luminal surface of the epididymal tubular epithelium, within the cytoplasm of parathyroid parenchymal cells and focally within the colloid of thyroid follicles. Other normal tissues do not express similar or cross-reacting antigens. RCC1 is expressed by most primary and metastatic renal cell carcinomas.
