title: Atypical case of oral lichen planus in a pediatric patient: clinical presentation and management.
abstract: Lichen planus (LP) is a mucocutaneous disease of unknown etiology that is relatively common in adults but rarely present in childhood. LP has been documented in dental and medical literature; however, there are few cases with oral involvement in children. The purpose of this paper was  to report an unusual case of oral lichen planus involving the upper lip in a 7-year-old girl. A diagnosis was made based on clinical examination and histopathology features. The treatment consisted of topical corticosteroid and intralesional injection. After treatment with an intralesional  corticosteroid, a complete re- mission of lesions involving the lip was observed. The 3-year follow-up, however, revealed asymptomatic lichenoid bilaterally affecting the buccal mucosa. The patient is currently under regular review.
