title: Oral lichen planus.
abstract: A 42-year-old woman presented with a 2-year history of persistent, gray-white lip discoloration and discomfort that had not improved after empiric treatment with topical 5-fluorouracil cream. Histopathologic examination demonstrated interface dermatitis with epidermal atrophy. A diagnosis of oral lichen planus was made based on clinicopathologic correlation, and treatment with topical tacrolimus ointment was initiated.
