Oral lichen planus: A case series

Oral reticular lichen planus (OLP) is a common mucocutaneous disease of uncertain cause. The disease seems to be autoimmune disease in which the apoptosis is triggered by CD8+T cells and non-specific mechanisms such as activation of matrix metalloproteinase and degranulation of mast cell. It is most often reported in patients with 30–60 years of age, group with a gender predilection, and female-to-male ratio of 1.4:1. This article is a case series of different forms and appearances of OLP with etiopathogenesis, clinical presentation, oral findings, diagnosis, malignant transformation potential, and treatment of OLP.
