    The majority of conventional leukoplakia remains constant and only a subset progress to high-grade dysplasia or invasive carcinoma. A less recognized form known as proliferative verrucous leukoplakia (PVL) represents a unique progressive and elusive variant. Identifying patients with this form can only be achieved through the keen clinical observation of the temporal gross and histologic progression in individual patients with squamous cell carcinoma.

Patients with this condition represent a unique clinically and pathologically progressive characteristic from conventional leukoplakia. Because of the lack of defined pathologic lesions, identifying patients with the early diagnosis of PVL is challenging. Read More
