Lichen Sclerosus: Symptoms, Treatment and UK Online Doctor Guide

Lichen sclerosus is a long-term (chronic) inflammatory skin disorder. Although it can affect any part of the body, it most frequently develops in the genital and anal regions. In the UK, it is most commonly diagnosed in women over the age of 50, but it can also affect men and children.

The condition causes the skin to become thin, white, and crinkled—often described as having a 'cigarette paper' texture. Because the skin becomes fragile, it can itch intensely and bleed or blister easily. While lichen sclerosus is not contagious and cannot be spread through sexual contact, it is a condition that requires medical monitoring to ensure the skin remains healthy and to manage discomfort.

Symptoms of lichen sclerosus can vary from person to person. Some individuals may have very mild symptoms, while others experience significant distress. Common signs to look out for include:

• White patches: Small, shiny white spots that may grow into larger, thin patches of skin.
• Intense itching: This is often the most common symptom and can be particularly troublesome at night.
• Skin fragility: The skin may tear easily, leading to small red or purple spots (purpura) or painful splits (fissures).
• Painful intercourse: In women, changes to the skin around the vaginal opening can make sex uncomfortable.
• Discomfort during urination: If the skin around the urethra is affected, it may sting when passing urine.
• Phimosis in men: In males, the condition can affect the foreskin, making it difficult to retract.

The exact cause of lichen sclerosus remains unknown, but it is widely believed by medical professionals in the UK to be an autoimmune condition. This means the body’s immune system mistakenly attacks its own healthy skin cells. There is also evidence suggesting a genetic link, as the condition sometimes runs in families.

It is important to note that lichen sclerosus is not caused by poor hygiene, and it is not a form of cancer. However, individuals with lichen sclerosus have a slightly higher risk of developing a specific type of skin cancer (squamous cell carcinoma) in the affected area, which is why regular check-ups with a GP or specialist are vital.

Following NICE (National Institute for Health and Care Excellence) and BAD (British Association of Dermatologists) guidelines, the primary treatment for lichen sclerosus is the use of very potent topical corticosteroid creams or ointments, such as clobetasol propionate.

Topical Steroids

Steroid creams help to reduce inflammation and itching, preventing the condition from worsening and reducing the risk of scarring. A typical treatment plan involves applying the cream daily for several weeks, before tapering down to a maintenance dose once or twice a week.

Emollients

Using soap substitutes and moisturising emollients is highly recommended. Standard soaps and shower gels can be drying and irritating to sensitive skin. Emollients help to protect the skin barrier and reduce the risk of tearing.

Surgical Intervention

Surgery is rarely needed for women but may be considered for men if the condition has caused severe narrowing of the foreskin (phimosis). In such cases, a circumcision may be recommended by a urologist.

If you have noticed persistent itching or unusual white patches in the genital area, it is important to seek medical advice promptly. Many patients feel embarrassed about these symptoms, but GPs are trained to handle these concerns professionally and discreetly.

Speaking to an online doctor in the UK can be an excellent first step. During a video consultation, you can describe your symptoms and discuss your medical history. An online GP can:

• Assess the likelihood of lichen sclerosus based on your description and symptoms.
• Provide guidance on the correct use of steroid creams and emollients.
• Issue a private prescription for necessary treatments if appropriate.
• Advise on whether you need a physical examination or a referral to a dermatologist or gynaecologist for a biopsy.
• Provide ongoing support for managing flare-ups.

Alongside medical treatment, certain lifestyle adjustments can help manage symptoms and protect fragile skin:

• Avoid irritants: Use plain water or a soap substitute for washing. Avoid scented wipes, bubble baths, and feminine hygiene deodorants.
• Gentle drying: Pat the area dry gently with a soft towel rather than rubbing.
• Breathable clothing: Wear loose-fitting cotton underwear and avoid tight-fitting trousers or leggings.
• Lubrication: Use a plain emollient or medical-grade lubricant to protect the skin during sexual activity.
• Avoid cycling: If symptoms are active, pressure from a bike saddle may cause further irritation.
