Histology of tissue samples. Frozen sections of normal kidney with glomerulus in center (A) and clear cell RCCa (B). Representative paraffin sections of clear cell (C, E, G) and chromophobe RCCa (D, F, H). Immunohistochemical stains for CD 31 (E and F) and CD 3 (G and H). Note that the clear cell tumor has an the extensive network of CD 31-positive vessels (E) and numerous scattered CD 3-positive lymphoctyes (G). In contrast, in the chromophobe there is a relative paucity of vessels (F) and few T cells (H). Original magnification:A, B 100× C – H 200×. Staining: A – D, hematoxylin and eosin; E – H, diaminobenzidine immunoperoxidase with hematoxylin.
