Proliferative verrucus leukoplakia: A case series

Oral proliferative verrucous leukoplakia (OPVL) is a rare form of oral leukoplakia first reported in 1985. It is a longterm progressive condition, which develops initially as a white plaque of hyperkeratosis that eventually becomes a multifocal disease with confluent, exophytic, and proliferative features. It has no racial preference with female predilection, associated with various factors including human papillomavirus (HPV) association, genetic susceptibility, and long-standing low-grade traumatic factors. The malignancy transformation rate varies from 0.13 to 17.5% with frequent recurrences. Here, we have reported two cases of PVL seen over the tongue and palate. It is confirmed by clinical and histopathological features and treated with Vitamin A and its supplements and a long-term follow-up showed no recurrence, and hence, Vitamin A has proven as a potent treatment option of PVL by its antioxidant and epithelialization property.
