Lichen planus occurs when the immune system attacks cells of the skin or mucous membranes. On skin, lichen planus appears as purplish, itchy, flat-topped shiny bumps. On mucous membranes, such as in the mouth, it forms lacy white patches, sometimes with painful sores. Lichen planus usually goes away on its own over time. If symptoms are bothersome, topical creams and oral antihistamines may help.
