Lichen Sclerosus in Women: Symptoms, Causes, and UK Treatment Options

Lichen sclerosus is a chronic, long-term inflammatory skin condition that primarily affects the genital and anal areas. In women, it most frequently occurs on the vulva (the external female genitals) and the skin around the anus. It is most commonly diagnosed in women over the age of 50, particularly those who have completed the menopause, though it can occasionally affect younger women and children.

Affected skin typically becomes thin, white, and crinkled—often described as having a 'tissue paper' or 'parchment-like' appearance. If left untreated, the inflammation can lead to the skin becoming fragile, prone to tearing, and eventually scarring. This scarring can cause the labia to shrink or the opening of the vagina to narrow, which can make physical activity or sexual intercourse uncomfortable.

It is important to understand that lichen sclerosus is not an infection. It is not contagious, and it is not caused by poor hygiene. UK health experts believe it is likely an autoimmune condition where the body’s immune system mistakenly attacks healthy skin cells, though a definitive cause is still being researched.

In the early stages, lichen sclerosus may not cause any noticeable symptoms, but as it progresses, most women experience significant discomfort. Recognizing the signs early is key to successful management. Symptoms typically include:

• Intense Itching (Pruritus): This is often the most distressing symptom and is frequently worse at night, sometimes disrupting sleep.
• White Patches: Small, white, slightly raised spots that may eventually join together to form large, thin, shiny patches.
• Soreness and Burning: The skin may feel tender or raw, particularly during urination or after friction.
• Fragile Skin: The skin may tear easily, leading to small bright red or purple bruises (purpura) or ulcers.
• Painful Intercourse: Changes in skin elasticity and narrowing of the vaginal opening can make sex painful (dyspareunia).
• Anal Discomfort: Itching or tearing around the anus, which can occasionally make passing stools painful.

Because these symptoms overlap with other conditions like vaginal thrush or dermatitis, many women in the UK often delay seeking help, assuming it is a simple infection. If symptoms do not clear up with over-the-counter anti-fungal treatments, a professional assessment is necessary.

The exact cause of lichen sclerosus remains unknown, but current NICE (National Institute for Health and Care Excellence) guidelines suggest a combination of factors. The leading theory is that it is an autoimmune disorder. This is supported by the fact that many women with lichen sclerosus also have other autoimmune conditions, such as thyroid disease, vitiligo, or pernicious anaemia.

Other contributing factors may include:

• Hormonal Changes: The prevalence among post-menopausal women suggests that low oestrogen levels may play a role in its development.
• Genetic Predisposition: There is some evidence that the condition can run in families.
• Trauma or Injury: Some patients report that the condition appears on skin that has previously been damaged or scarred (known as the Koebner phenomenon).

It is crucial to note that while lichen sclerosus is not cancerous, the chronic inflammation associated with it slightly increases the risk of developing squamous cell carcinoma (a type of skin cancer) in the affected area. This occurs in approximately 1% to 5% of cases, highlighting the need for lifelong monitoring.

While there is currently no permanent cure for lichen sclerosus, the symptoms can usually be very well controlled. The primary goal of treatment is to reduce inflammation, relieve itching, and prevent scarring.

Ultrapotent Corticosteroids

The gold-standard treatment involves the use of a very strong steroid cream or ointment, most commonly Clobetasol propionate 0.05% (Dermovate). Initially, this is applied once daily for several weeks to get the inflammation under control. Following this 'induction' phase, the frequency is gradually reduced to a maintenance dose, such as twice weekly.

Emollients and Skin Care

Using a soap substitute (emollient) is essential for protecting the skin barrier. Standard soaps and bubble baths can be highly irritant to lichen sclerosus skin. UK GPs often recommend using a plain emollient cream both for washing and as a moisturiser throughout the day to keep the skin supple.

Secondary Treatments

In cases where steroid creams are not effective, a specialist may suggest calcineurin inhibitors (such as tacrolimus) or, in rare instances of severe scarring, surgical intervention. However, surgery is generally avoided as the condition often recurs at the site of the operation.

Discussing genital symptoms can feel embarrassing, but seeking professional advice is the only way to ensure you receive the correct treatment. Many women prefer to speak to a GP online as it offers a discreet and convenient way to discuss symptoms from the privacy of their own home.

You should book an online consultation if:

• You have persistent itching or soreness in the genital or anal area that does not respond to thrush treatment.
• You have noticed new white, thickened, or crinkled patches of skin.
• You are experiencing pain during intercourse or when passing urine.
• You have been previously diagnosed and your symptoms are flaring up despite treatment.
• You need a repeat prescription for your maintenance steroid treatment and require a review of your progress.

An online doctor can review your symptoms, provide advice on the appropriate use of steroid ointments, and help determine if you need an in-person physical examination or a referral to a gynaecologist or dermatologist for a biopsy.

In addition to medical treatment, certain lifestyle adjustments can significantly improve comfort levels for women living with lichen sclerosus in the UK:

• Avoid Irritants: Switch to non-biological laundry detergents and avoid using scented wipes, feminine deodorants, or perfumed soaps in the genital area.
• Wear Loose Clothing: Opt for cotton underwear and avoid tight-fitting trousers or leggings that can cause friction.
• Barrier Creams: Apply a thick layer of emollient or petroleum jelly before swimming in chlorinated pools or before passing urine if the skin is broken.
• Gently Pat Dry: After washing, gently pat the area dry with a soft towel rather than rubbing.
• Monitor Your Skin: Perform a self-examination once a month. Use a mirror to look for any new lumps, ulcers, or changes in the appearance of the white patches.
