General Discussion

Lichen Planus is a rare, recurrent, itchy rash or area of inflammatory eruptions (lesions) of unknown origin characterized by shiny reddish-purple spots on the skin and gray-white ones in the mouth. The disorder may present as itchy spots on the wrist, legs, torso, genitals, mouth, or lips. The eruptions may appear as small separate, angular spots that may coalesce into rough scaly patches. This disorder is frequently accompanied by oral lesions of the mucous membranes that line the mouth. The disorder affects women more frequently than men.
