Lichen planus (LP) is an idiopathic inflammatory condition that may affect the skin, mucosa, nails, and/or the scalp. Mucosal involvement may include oral, esophageal, and/or genital lesions.1,2,3


Classically, cutaneous LP presents with purple (violaceous), pruritic, polygonal papules or plaques, colloquially referred to as the “4 Ps.”

Cutaneous LP most commonly presents between 30 and 60 years of age. LP is uncommon in children, but pediatric cases have been documented.4 Cutaneous lesions tend to spontaneously remit in 1 to 2 years with no treatment; however, oral lesions may persist for 5 years, and erosive lesions may not self-resolve.
