Oral warty dyskeratoma

Abstract

An elderly woman had a small verrucose hyperkeratotic papule on the hard palate. Histologic examination showed the lesion to be a warty dyskeratoma. Warty dyskeratoma may represent an abnormal keratinization response to intraoral trauma or inflammation. All eight previously reported cases are reviewed. Clinically, the lesions appeared as verrucose hyperkeratotic papules or as focal mucosal depressions, sometimes filled with keratin. Eight of nine lesions were located on the hard palate or on an alveolar ridge.
