Figure 4

Immunohistochemical evaluation in cancer specimens. In clear cell carcinoma a membrane positivity is observed ((a) H&E; (b), (b) inset, TCTP staining; ((a)-(b)) ×200; (b) inset ×400); in papillary carcinoma ((c) H&E; (d) TCTP staining; ((c)-(d)) ×100) and in collecting duct carcinoma, the staining is cytoplasmic ((e) H&E; (f) TCTP staining; ((e)-(f)) ×200). The comparison with nonneoplastic tissue from the same samples is shown ((g) TCTP stain, ×200) as well as the negative control ((h) ×200).
