Understanding Lichen Planus
Lichen planus is an inflammatory condition that can affect the skin, mouth, nails, scalp or genital areas. Skin lesions are often itchy, flat-topped bumps that may look purple, brown or grey. It is not a contagious infection. The affected site matters because some forms need ongoing monitoring or treatment to prevent lasting damage.
Common symptoms
- Itchy flat-topped bumps, often around wrists or ankles.
- White lace-like areas or soreness inside the mouth in some people.
- Nail changes or scalp inflammation in certain forms.
Causes and contributing factors
The condition involves immune-mediated inflammation. The exact trigger is often unknown, and some medicines can cause a similar lichenoid eruption. Do not stop a prescribed medicine without discussing the possibility with its prescriber.
How the condition is assessed
A clinician examines the relevant skin and may check the mouth, scalp and nails. A biopsy or other tests can help confirm uncertain cases. Mouth or genital symptoms may need coordinated assessment with other appropriate specialists.
Care and treatment considerations
Treatment is selected for the site, symptoms and risk of scarring. Avoid scratching and products that aggravate sore areas. Prescription anti-inflammatory treatment and follow-up may be needed; ordinary rash creams are not interchangeable between the mouth, genital skin and scalp.
When to seek medical help
Arrange early review for scalp pain or hair loss, progressive nail damage or painful mouth lesions. A persistent ulcer, new lump or changing lesion in a previously affected area needs prompt examination.
Patient questions
Can I pass lichen planus to someone else?
No. Lichen planus itself does not spread through touch, shared utensils or household contact.
Does every form have the same outlook?
No. Skin-only disease and disease affecting the scalp, nails or mucosal surfaces can behave differently and need different follow-up.
