Proliferative Verrucous Leukoplakia and Verrucous Carcinoma-A Hybrid Epithelial Tumour

ABSTRACT

White lesions are relatively frequent in the oral cavity with a prevalence of approximately 24.8%. Among them is oral leukoplakia with a prevalence rate of 0.2–3.6%. There were various debates about the verrucous carcinoma and PVL (proliferative verrucous leukoplakia) being different entities or a part of spectrum at different stages of the disease process. In this article we are reporting a case with coexistence of two different histological features in the form of verrucous carcinoma and PVL of oral cavity with a need to throw some light to understand the pathogenesis of premalignant lesions.
