Lichen nitidus is a chronic inflammatory disease of unknown etiology characterized by 1–2 mm discrete and uniform shiny flat-topped pale flesh-colored or reddish-brown papules that may appear as hypopigmented against dark skin. Occasionally minimal scaling is present or can be induced by rubbing the surface of the papules. The disease usually affects children and young adults and is painless and usually nonpruritic although protracted itching may occur in some cases.
