Abstract
Lichen sclerosus et atrophicus affecting only the oral mucosa is extremely rare. We report here a case of oral lichen sclerosus et atrophicus presenting as a white, flat lesion involving the right buccal and labial mucosa and vermillion border. The diagnosis was based on histopathologic features. Treatment with intralesional corticosteroid was successful in reducing the size of the lesion and the symptoms of the patient. A free gingival graft was also performed to restore the lost attached gingiva. No recurrence of the lesion was found after a 1-year follow-up period, and no skin or genital lesions developed during the 3 years of treatment.
