Demographic and clinicopathological comparison among oral lichen planus, lichenoid lesions and proliferative verrucous leukoplakia: a retrospective study.

Background: Clinicopathological diagnosis and follow-up of oral lichen planus and leukoplakia are necessary due to its potential for malignant transformation and the need to differentiate it from other lichenoid diseases and proliferative verrucous leukoplakia. This study aimed to classify and compare sociodemographic and clinicopathological features among patients with oral lichen planus, oral lichenoid lesions and proliferative verrucous leukoplakia.

Methods: A transversal observational study in which oral leukoplakia and oral lichen planus patients were surveyed at the Oral Pathological Anatomy Service and Applied Biotechnology Laboratory was conducted.
