Clinical features and treatment outcomes of nail lichen planus: A retrospective study

Abstract

Lichen planus is a benign, chronic, mucocutaneous disorder that affects the skin, mucosae, and nails. The occurrence of nail lichen planus has been reported to be about 10% to 15%.1,2 Nail lichen planus is more common in adults than in children, and it mostly affects the fingernails rather than the toenails.3 The many nail abnormalities found in nail lichen planus depend on its pathologic location: the nail matrix or the nail bed. Dorsal pterygium is an irreversible and classic finding in nail lichen planus.
