Lichen planus

Abstract

Oral lichen planus is a chronic inflammatory autoimmune disease affecting the oral mucous membrane. Its causes may include chronic medication use, metal denture friction, stress, and emotional disturbance. It is characterized by swelling and irritation with slight desquamation of the membrane, as well as Wickham striae under dermoscopy. Another common benign condition of skin hyperplasia is lichenoid keratosis, which involves an erythematous rash in the trunk or upper limbs triggered by friction. Although the two aforementioned conditions may occur separately, simultaneous sighting of two to three lesions in the skin has been reported.
