Lichen sclerosus is a long-term dermatological condition characterised by inflammation and thinning of the skin, most often affecting the genital area. The exact cause is not fully understood, but it is thought to involve a combination of autoimmune, genetic, and hormonal factors. The condition is not infectious and cannot be passed between individuals.
Symptoms can range from mild to severe and may progress over time. In women, common features include:
If left untreated, lichen sclerosus can lead to irreversible anatomical changes, including labial fusion, narrowing of the vaginal opening, and clitoral burying. These changes may significantly affect sexual function and daily comfort.
Diagnosis is primarily clinical and based on the characteristic appearance of the affected skin.
Additional investigations may be required in certain situations:

The main aims of treatment are symptom relief, prevention of skin damage, and early detection of malignant change.
High-potency topical corticosteroids are the cornerstone of management. These reduce inflammation, relieve symptoms, and help prevent disease progression. Treatment usually involves an initial intensive phase followed by long-term maintenance therapy.
Supportive measures play an important role in symptom control:
Patients who do not respond to standard treatment, or who develop significant scarring or anatomical changes, should be referred to a specialist for further assessment.
For selected patients with refractory symptoms, additional therapies may be considered:
Emerging therapies currently under investigation include:

Lichen sclerosus is associated with a small but significant increased risk of vulval squamous cell carcinoma, estimated at approximately 5%. Regular follow-up and ongoing treatment are essential to reduce this risk.
Patients are encouraged to:
Is lichen sclerosus curable?
No. It is a chronic condition, but symptoms can be effectively controlled with appropriate long-term treatment.
Is it contagious?
No, lichen sclerosus is not contagious.
Does it increase cancer risk?
Yes. There is a small increased risk of vulval cancer, which is why regular monitoring is important.
How often are check-ups needed?
An initial review is recommended around three months after starting treatment, followed by annual follow-up if the condition is stable.
What can improve daily comfort?
Using soap-free emollients, wearing loose cotton underwear, avoiding irritants, and minimising scratching can significantly improve comfort.
You should seek medical review if you notice:
Lichen sclerosus is a long-term condition that requires ongoing care, but with early diagnosis and appropriate management, most women achieve good symptom control and maintain quality of life. Regular follow-up and adherence to treatment are essential for preventing complications and detecting changes early.
