Abstract
Lichen planus, a chronic inflammatory skin disorder, presents with pruritic, polygonal, and flat-topped papules and plaques. It encompasses not only the skin but also mucous membranes, nails, and hair follicles. Diagnosis relies on all the clinical and biopsy reports. The etiology of oral lichen planus (OLP) is multifactorial, with genetic, immunological, and environmental factors playing significant roles. Frequently utilized therapies encompass topical corticosteroids, calcineurin inhibitors, and systemic immunomodulatory medications. Management should be tailored to disease severity and the specific site of involvement. Lichen planus can present in papular, hypertrophic, atrophic, erosive, or erythematous forms. In this report, we present a case of a 28-year-old male patient who presented with bilateral white striations on the buccal mucosa and an erythematous lesion on the right buccal mucosa causing significant discomfort. The patient was treated with corticosteroids, resulting in marked symptomatic relief and partial lesion regression over a follow-up period of six months. This case underscores the importance of early diagnosis and tailored therapeutic strategies in managing OLP to improve patient outcomes.
