CK19 staining expression and localization in distant mucosa in HPV−/HPV+ cancers. a. CK19 expression was distributed mostly in the basal layers in distant mucosa from HPV− OSCC. b. CK19 staining was generally moderate in intensity, localized both at basal and more superficial epithelial layers in distant mucosa from HPV+ OSCC.
