Figure 1.

Images of atypical squamous epithelium cases with patchy p16 reaction: (A–F). The same sample stained with HE and p16 at 200× magnification. Panels (A), (C), and (E) show HE staining, while panels (B), (D), and (F) show corresponding p16 staining.

Figure 2.

Only case in the group with atypical squamous epithelium with patchy p16 expression and positive reaction for E4 human papillomavirus (HPV). The tissue was positive for HPV16 and 31 and the follow-up was negative. The same section at 100x magnification: (A) HE staining; (B) p16 staining, (C) Ki67 staining, (D) E4 HPV staining, (E) Nanog staining, F. SOX11 staining.
