title: Lichen planus actinicus.
abstract: A 53-year-old woman presented for evaluation and treatment of discrete, violaceous, annular plaques on the forehead and cheeks. The biopsy specimen and the clinical presentation were consistent with lichen planus actinicus. Lichen planus actinicus is a photosensitive variant of lichen planus that can present with annular, melasma-like, dyschromic, or violaceous plaques in sun-exposed areas. The clinical manifestations of lichen planus actinicus and treatments are discussed.
