Lichen Planus Overview
Learn About Lichen Planus
Lichen planus is a condition that forms a very itchy rash on the skin or in the mouth.
Lichen ruber planus
The exact cause of lichen planus is unknown. It may be related to an allergic or immune reaction.
Risks for the condition include:
- Exposure to certain medicines, dyes, and other chemicals (including gold, antibiotics, arsenic, iodides, chloroquine, quinacrine, quinine, phenothiazines, and diuretics)
- Diseases such as hepatitis C
Lichen planus mostly affects middle-aged adults. It is less common in children.
Mouth sores are one symptom of lichen planus. They:
- May be tender or painful (mild cases may not cause pain)
- Are located on the sides of the tongue, inside of the cheek, or on the gums
- Look like bluish-white spots or pimples
- Form lines in a lacy network
- Gradually increase in size
- Sometimes form painful ulcers
Skin sores are another symptom of lichen planus. They:
- Usually appear on the inner wrist, legs, torso, or genitals
- Are extremely itchy
- Have even sides (symmetrical) and sharp borders
- Occur alone or in clusters, often at the site of a skin injury
- May be covered with thin white streaks or scratch marks
- Are shiny or scaly looking
- Have a dark, violet color
- May develop blisters or ulcers
Other symptoms of lichen planus are:
- Dry mouth
- Hair loss
- Metallic taste in the mouth
- Ridges in the nails
The goal of treatment is to reduce symptoms and speed healing. If your symptoms are mild, you may not need treatment.
Treatments may include:
- Antihistamines
- Medicines that calm down the immune system (in severe cases)
- Lidocaine mouthwashes to numb the area and make eating more comfortable (for mouth sores)
- Topical corticosteroids or oral corticosteroids to reduce swelling and lower immune responses
- Corticosteroid shots into a sore
- Vitamin A as a cream or taken by mouth
- Other medicines that are applied to the skin
- Dressings placed over your skin with medicines to keep you from scratching
- Ultraviolet light therapy

Lichen planus is usually not harmful. Most often, it gets better with treatment. The condition often clears up within 18 months, but may come and go for years.
If lichen planus is caused by a medicine you are taking, the rash should go away once you stop the medicine.
Mouth ulcers that are present for a long time may develop into oral cancer.
Contact your provider if:
- Your skin or mouth lesions change in appearance
- The condition continues or gets worse, even with treatment
- Your dentist recommends changing your medicines or treating conditions that trigger the disorder
Summary: This randomized, double-blind clinical trial evaluates the therapeutic effects of curcumin in nanogels compared to 0.1% fluocinolone acetonide oral paste in the management of atrophic-erosive oral lichen planus (OLP). The study aims to determine whether curcumin nanogels, a natural treatment with enhanced bioavailability, are as effective and better tolerated than standard corticosteroid therapy.
Summary: Bromelain, an enzyme extract derived from pineapples, has shown promise due to its anti-inflammatory and wound-healing properties. However, its efficacy in treating oral mucosal ulcers remains unexplored. This study aims to provide clinical evidence on the efficacy of bromelain for managing OLP, potentially offering a safer and more effective treatment option.
