Lichen planus is a long-term inflammatory skin condition that causes a rash on one or more parts of the body. It can affect skin, inside of the mouth (oral lichen planus), scalp, nails, genital area (vulva, vagina, or penis). The rash usually appears as small, raised, flat-topped bumps or patches that may be itchy or uncomfortable.
Is lichen planus an autoimmune disease?
Lichen planus is not officially classified as an autoimmune disease, but it behaves like one. It happens when the body’s immune system mistakenly attacks the skin or mucous membranes, causing inflammation.
The exact reason why this immune reaction occurs is not known.
What is the difference between lichen planus and lichen sclerosus?
Both are skin conditions that affect sensitive areas, but they are different:
Lichen planus can affect the skin, mouth, nails, scalp, and genitals.
Lichen sclerosus mainly affects the genital and anal area and causes the skin to become thin, itchy, and scarred. It is more common after menopause and rarely affects the mouth.
Which parts of the body are commonly affected?
Lichen planus commonly appears on:
Wrists and forearms
Ankles and lower legs
Back of the hands
Inside the cheeks and tongue
About half of people with lichen planus develop oral lichen planus.
What are the symptoms of lichen planus?
Symptoms depend on the area affected and may include:
Small, raised, flat bumps on the skin or genitals
White or lace-like patches inside the mouth
Red, sore areas or open sores in severe cases
Itching (especially on the skin)
Nail changes such as discoloration, splitting, slow growth, or nail loss
Lichen planus itself is usually not painful, but scratching can lead to infection and pain.
What causes lichen planus flare-ups?
Certain factors may trigger or worsen symptoms, such as:
Hepatitis C infection
Some vaccines
Painkillers like NSAIDs
Medicines for heart disease, arthritis, or high blood pressure
Exposure to certain metals, chemicals, or pigments
Stress
Is lichen planus contagious?
No. Lichen planus is not contagious. It cannot spread through touch, sexual contact, or sharing personal items.
How is lichen planus diagnosed?
Doctors usually diagnose lichen planus by:
Examining the skin, mouth, or genital area
Reviewing symptoms
They may look for classic signs known as the “six Ps”:
Itchy (pruritic)
Purple
Flat-topped (planar)
Many-sided (polygonal)
Small bumps (papules)
Patches (plaques)
If needed, tests may include:
Skin or mouth biopsy
Allergy testing
Blood test for hepatitis C
Is there a cure for lichen planus?
There is no permanent cure, but many cases improve on their own over time.
Skin lichen planus may clear in months to a few years
Oral lichen planus may take up to five years
Treatment helps control symptoms and reduce flare-ups.
How is lichen planus treated?
Treatment depends on severity and location and may include:
Steroid creams or ointments
Antihistamines for itching
Light therapy (phototherapy)
Immune-suppressing medicines (for severe cases)
Retinoid creams or tablets (used carefully, especially in pregnancy)
How is oral lichen planus managed?
If the mouth is affected, symptoms may improve by:
Maintaining good oral hygiene
Gentle brushing and flossing
Avoiding mouth injuries
Replacing dental fillings if metal allergy is suspected
Can stress make lichen planus worse?
Yes, stress can trigger or make flare-ups worse.
Emotional stress signs include:
Anxiety or depression
Irritability
Trouble concentrating
Using alcohol or tobacco to cope
Physical stress signs include:
Poor sleep
Digestive problems
Muscle tension
Body aches
Managing stress can help lower your symptoms.
What foods should be avoided?
If oral lichen planus is present, you should avoid food like:
Spicy foods
Acidic foods (citrus fruits, tomatoes)
Hot foods and drinks
Alcohol
Smoking or tobacco
How is lichen planus different from psoriasis?
Both conditions cause skin rashes, but:
Psoriasis usually causes thick, scaly patches
Lichen planus causes flat, smooth bumps and may affect the mouth and genitals
What can I expect in the long term?
Lichen planus is manageable. Many people improve with time and treatment.
If it affects the genital area, it may cause discomfort during sex, but it is not sexually transmitted and does not affect fertility.
Can lichen planus be prevented?
There is no known way to prevent lichen planus.
When should I see a doctor?
Consult your healthcare provider if:
New symptoms appear
Symptoms do not improve with treatment
The rash lasts longer than expected
The skin looks infected or very painful
