Proliferative Verrucous Leukoplakia: A Potentially Malignant Disorder Involving Periodontal Sites

Abstract

The importance of PVL awareness for periodontists is underscored by the frequency of gingival involvement and the high prevalence of malignant transformation on masticatory mucosa, which usually can be suspected because of the onset of warning signs, such as rapid growth of verrucosity, area of erosion or ulceration, acquisition of red areas, induration, and positive response to toluidine blue staining.
