Keratin antibody localization in head and neck tissues and neoplasms

Immunohistochemical staining for keratin proteins may be useful as a diagnostic parameter in head and neck neoplasms. Our study evaluates the keratin antibody staining properties of normal tissues as well as neoplastic and non-neoplastic head and neck lesions from surgical procedures performed on 100 patients. The results indicate that the anti-keratin antibody technique can be helpful in several areas of head and neck pathology.
