Lichen planus (LP) is a common inflammatory disease that affects the skin, mouth, genitals or all of them. The name “lichen” refers to the lichen plant which grows on rocks or trees, and “planus” means flat.
Skin LP affects men and women equally, but oral LP affects women twice as often as men. LP affects about one to two percent of the general population. It occurs most frequently in middle-aged adults. The cause of LP is not known. LP is not infectious and it does not appear to be inherited. Most dermatologists believe it can be classified as an autoimmune disease. This means that white blood cells which usually fight germs begin to attack the normal parts of the skin, mucous membranes, hair, and nails. Sometimes, lichen planus-type rashes which occur as allergic reactions to medications for high blood pressure, heart disease, and arthritis. Identifying and stopping the drug helps clear up the condition within a few weeks. Sometimes LP can also be associated with hepatitis C. Lichen planus on the wrist
LP of the skin is characterized by itchy, reddish-purple, flat-topped bumps. Some may have a white lacy appearance called Wickham’s Striae. They can be anywhere on the body, but seem to favor the inside of the wrists and ankles. The disease can also occur on the lower back, neck, legs, genitals, the scalp and nails. There may be thick patches (hypertrophic LP) especially on the shins. Blisters are rare and seen in bullous LP. A skin biopsy may be needed to confirm the diagnosis.
Many cases of LP go away within two years often leaving a dark brown discoloration on the skin. These stains may eventually fade with time without treatment. About 20 percent cases will have a second attack of LP.
There is no known cure for LP but treatment is often effective in relieving itching and in improving the appearance of the rash until it goes away. Since every case of LP is different, no one treatment is perfect. Topical corticosteroid creams, ointments, or other anti-inflammatory drugs, and oral antihistamines taken by mouth, cortisone taken internally, ultraviolet light treatment called PUVA are some of the common modes of therapy. Since new areas of LP can form in the damaged skin, try to avoid injury.
It most commonly occurs inside of the cheeks, but can affect the tongue, lips, and gums. Oral LP is more difficult to treat and typically lasts longer than LP on the skin. About 20 percent cases who have oral LP also have skin LP.
