Lichen nitidus is a chronic inflammatory disease of unknown cause [1] characterized by 1–2 mm, discrete and uniform, shiny, flat-topped, pale flesh-colored or reddish-brown papules[2][3] that may appear as hypopigmented against dark skin. Occasionally, minimal scaling is present or can be induced by rubbing the surface of the papules.[3] The disease usually affects children and young adults[4] and is painless and usually nonpruritic, although protracted itching may occur in some cases.[3][5] It is sometimes referred to by dermatologists as "mini lichen planus".
