Lichen planus (LIE-kun PLAY-nus) usually appears as purplish, often itchy, flat-topped bumps (lesions), most often located on the inner forearm and near the wrists or ankles. Other common locations include the lower back, neck and legs.
The condition rarely worsens after the first couple of months, but it may persist for months or years. Mild cases may need relatively simple at-home care or no treatment. When symptoms are severe, such as pain or significant itching, drug treatment may improve symptoms.
Lichen planus may also affect mucous membranes, genitals, the scalp or nails. The lesions associated with these sites generally cause more discomfort. The symptoms are more difficult to manage, often persist for long periods and often recur after initial healing.

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.
