Lichen striatus presents as a linear or curvilinear slightly scaly papules that coalesce into a plaque. The color of these papules can be diverse from skin-colored or slightly pink in lighter skin tones to purple or white in darker complexions. Usually they follow the lines of Blaschko. When the lesions resolve they can leave hypo- or hyperpigmentation. Other linear conditions should be considered such as linear lichen planus, linear psoriasis, or inflammatory linear verrucous epidermal nevus.
