Lichen planus (LIE-kun PLAY-nus) is an inflammatory condition that can affect your skin and mucous membranes.
On the skin, lichen planus usually appears as purplish, often itchy, flat-topped bumps. When mucous membranes are affected — such as tissues inside the mouth or vagina — lichen planus appears as lacy white patches or sores that can be painful.
Lichen planus can't be passed from one person to another. The disorder occurs when the immune system mounts an attack against cells of the skin or mucous membranes. The reason for this abnormal immune response is unknown.
Mild cases of lichen planus may need relatively simple at-home care or no treatment. When symptoms are severe, such as pain or significant itching, treatments may include drugs that suppress the immune system abnormalities.
