Abstract:
Lichen planus is a chronic inflammatory autoimmune disease in which autoantibodies are generated against the basal keratinocytes, leading to its degeneration. The prevalence of oral lichen planus (OLP) ranges from 0.5% to 2.2% of the population. We report a case of A 45-year-old female with reddish white patches on her left inner cheek region and tongue. The histology confirm the diagnosis of bullous lichen.
