Oral lichen planus (OLP) is a chronic inflammatory dermatosis of unknown etiology that often involves the mucous membranes. Most of the non-ulcerative type of OLP improved with topical and systemic medications and recurrence is common. Here, a 52-year-old male presented with a 10-year history of persistent, gray-white oral mucosal discoloration and discomfort that had not improved after empiric treatment with topical triamcinolone acetonide. Histopathologic examination confirmed the diagnosis of OLP. Treatments were given with intralesional triamcinolone acetonide, oral paste and even systemic steroids, but little improvement was noted. Finally, patient was cured by surgical excision. There was no relapse after 2 years follow up.
Key words: Oral lichen planus (OLP), steroids, surgical excision, relapse.
