Figure 4 : Immunohistochemistry.

(a) Keratin 7 positive immunoreactions in the outer epithelium, (b) show the β catenin immunoreaction in small nest keratin positive in necrosis areas (b) Vimentin was positive in cells of the stellate reticulum and the outer edge of the epithelium (c), and in (d) numerous vessels and fibroblast proliferation were observed in (d). Strongly positive immunoreaction for EVFG (e), and PDGF (f) in vessels and fibroblast proliferation are seen Ki-67 (g) shows more positivity reaction from normal appearance and in (h) is displayed Ki-67 positive reaction in the nucleoli and with a punctate appearance (IHQ stain x 400).
