Abstract:Frozen sections from squamous cell carcinomas (SCCs), basal cell carcinomas (BCCs), precancerous lesions (P.C.) and normal skin adjacent to lesions (N.S.) were studied by indirect immunoperoxidase for the detection of epithelial membrane antigen (EMA) and by PAP (peroxidase‐antiperoxidase) for total keratin (T.K.) and laminin (LM) to determine the significance of the appearance of neoantigens and the behavior of normal epidermal antigens during the process of carcinogenesis of the skin. Significant antigenic d… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
