Lichen planus pigmentosus (LPP) has thus far been described as a condition of unknown etiology which clinically differs from the classical lichen planus (LP) by exhibiting dark brown macules and/or papules mostly in exposed areas and flexural folds and a longer clinical course without pruritus or scalp, nail or mucosal involvement.
