Vulval Lichen Sclerosus: Symptoms, Causes, and Treatment in the UK

Lichen Sclerosus (LS) is a long-term inflammatory skin condition that most commonly affects the genital and anal areas. In women and people assigned female at birth, it typically occurs on the vulva. While it can affect people of any age, it is most frequently diagnosed in women over the age of 50, often coinciding with the menopause.

The condition causes the skin in the affected area to become thin, fragile, and white. If left untreated, the skin may scar, leading to the narrowing of the vaginal opening or the covering of the clitoris. Despite its appearance, it is important to remember that lichen sclerosus is not an infection, it is not sexually transmitted, and it is not caused by poor hygiene.

Symptoms of lichen sclerosus can range from mild to extremely distressing. Many patients describe the sensation as a persistent, 'burning' itch that is often worse at night. The main signs to look for include:

• White patches: Small, shiny white spots that can grow into larger, thinned, crinkled patches, sometimes described as looking like 'cigarette paper'.
• Intense itching: Pruritus is the most common symptom and can significantly impact sleep and quality of life.
• Soreness and discomfort: The skin may become so fragile that it tears easily, leading to small splits (fissures) or bruising/blood blisters.
• Pain during intercourse: Scarring or thinning of the skin can make sex uncomfortable or painful (dyspareunia).
• Changes in anatomy: Over time, the labia minora may shrink or 'fuse', and the clitoral hood may become buried.

The exact cause of lichen sclerosus remains unknown, but evidence-based research suggests it is likely an autoimmune condition. This means the body's immune system mistakenly attacks its own healthy skin cells. Statistics show that people with LS are more likely to have other autoimmune disorders, such as thyroid disease, vitiligo, or alopecia areata.

Hormonal changes also play a role, as the condition is most common when oestrogen levels are low. However, it can also affect children before puberty. While there is no definitive genetic link, about 10% of patients have a family history of the condition. Environmental triggers, such as previous skin trauma or chronic irritation, may also contribute to flares.

In the UK, the initial step is usually a physical examination by a GP. A doctor can often identify LS by the characteristic white, 'figure-of-eight' pattern around the vulva and anus. According to NICE (National Institute for Health and Care Excellence) guidelines, a diagnosis is often made clinically, but a referral to a gynaecologist or dermatologist may be necessary.

In some cases, a small skin biopsy may be performed. This involves taking a tiny sample of skin under local anaesthetic to confirm the diagnosis and rule out other conditions like lichen planus or vulval intraepithelial neoplasia (VIN). Regular check-ups are vital, as chronic inflammation carries a small (roughly 3-5%) risk of developing vulval squamous cell carcinoma.

While there is currently no cure for lichen sclerosus, it can be managed very effectively with the right treatment. The 'gold standard' treatment in the UK involves:

• Topical Steroids: A very potent steroid cream, such as Clobetasol Propionate (Dermovate), is used to dampen the inflammation. A typical starting regime involves applying the cream once daily for three months, gradually reducing the frequency as symptoms improve.
• Moisturisers (Emollients): Using a soap substitute and applying a thick emollient throughout the day helps protect the skin barrier and reduces irritation.
• Maintenance Therapy: Once the condition is under control, most patients move to a 'maintenance' dose—applying the steroid cream once or twice a week—to prevent flares and further scarring.

Discussing genital symptoms can often feel embarrassing, leading many women to suffer in silence for years. Using an online doctor in the UK can provide a more comfortable, private way to seek medical advice. If you have noticed itching that doesn't clear up with over-the-counter thrush treatments, or if you have seen white patches on your skin, you should speak to a GP.

During a GP consultation online, you can discuss your symptoms in detail. While a physical examination is necessary for a formal diagnosis, a GP can provide a preliminary assessment, discuss potential treatments, and provide a sick note if your symptoms are severely impacting your ability to work. They can also provide a referral to a specialist clinic if required.

Alongside medical treatment, lifestyle adjustments can significantly reduce discomfort:

• Avoid soap, bubble baths, and scented wipes; use plain water or a prescribed emollient for washing.
• Wear loose-fitting, breathable cotton underwear.
• Avoid tight clothing like leggings or jeans during a flare-up.
• Use a barrier cream (like Vaseline) before swimming in chlorinated water or cycling.
• Do not scratch the area, as this causes further trauma to the fragile skin.
