title: Keratinization in odontogenic tumors.
abstract: The potential of odontogenic epithelium to keratinize in the form of ghost cells is demonstrated in the histologic variants of a number of odontongic tumors. Although the cells lack keratohyaline granules, they do contain abundant tonofilaments and probably represent an altered form of keratin. The presence of this material in odontogenic tumors does not appear to alter clinical occurence or clinical behavior.
