Oral lichen planus clinical characteristics in Italian patients: a retrospective analysis

Oral lichen Planus (OLP) is a chronic inflammatory disease involving skin and mucous membranes. Its etiology is still uncertain whilst an autoimmune mechanism is known to be implicated. OLP is commonly considered a geriatric disease and gender differences in prevalence are clear, whereby females are generally more frequently affected than males more often during the 5th and 6th decades of life. Lesions are symmetrical and bilateral and the buccal mucosa is frequently involved. The risk of malignant transformation is extremely low. This study aims to describe both the clinical characteristics and the prevalence of OLP among a group of patients from Southern Italy. The results of the present study were compared to analogous retrospective studies.
