title: Proliferative verrucous leukoplakia: a case report.
abstract: Proliferative verrucous leukoplakia (PVL) is a particularly aggressive form of oral leukoplakia that is resistant to treatment and presents a high risk of recurrence and malignant transformation. This article describes the microscopic and clinical characteristics of one case of PVL, which initially presented as hyperkeratosis with mild dysplasia and posteriorly developed multifocal areas and verrucous carcinoma despite treatment.
