Reticular oral lichen planus (OLP) is a chronic inflammatory lesion that affects the mucosa of the oral cavity. Being in most cases asymptomatic, it is often detected incidentally during routine oral examination. This report presents the case of a 38-year-old male who consulted for mild burning sensation in his mouth while consuming acidic foods and liquids. Intraoral examination revealed bilateral reticular OLP on the buccal mucosa; diagnosis was confirmed histopathologically. Treatment with topical corticosteroid leaded to significant symptoms improvement. Yearly long-term follow-up was requested to observe the disease activity and to rule out any malignant transformation.
