• Figure 1. 

  (a) p53 immunostaining of verrucous carcinoma, showing more than 30% positively stained tumor cells (original magnification ×25). (b) CD44v9 immunostaining of verrucous carcinoma. Positive staining was localized to peripheral cells of tumor nests (original magnification ×10). (c) PCNA immunostaining of verrucous carcinoma. Positively stained cells were observed in tumor cells located near the basement membrane and paracentrally in tumor nests (original magnification ×50).
