Figure 3: Photomicrograph showing (a) CD34 membrane positive immunostaining with normal vascular endothelial cells acting as internal control. Also note the absence of the staining in surface epithelial cells (CD34, ×100). (b) Calretinin immunomarker showing positivity in and around the keratin within the squamous lobules highlighting the companion layer of outer root sheath (Calretinin, ×100). (c) Ki67 nuclear immunostaining with focal and peripheral reactivity (Ki67, ×100). (d) Immunostaining with p53 showing strong diffuse nuclear positivity (p53, ×100)
