16564 Lichen Sclerosus

Overview

Lichen sclerosus is a long-term skin condition that most often affects the genital and anal areas. It causes thin, white, patchy skin that can itch, hurt, or blister. It is not an infection and is not contagious, but it is a real medical condition that can be managed with treatment.

Lichen sclerosus is not rare, but it is often underdiagnosed because people may feel embarrassed to see a doctor. It affects around 1 in 100 to 1 in 60 people, though exact numbers are uncertain.

It is much more common in women, especially after menopause, but men and children can also get it. In men it usually affects the foreskin and tip of the penis. In children it can appear before puberty, often around the anus or genitals.

Symptoms

Common symptoms

• White, smooth or crinkled patches of skin on the genitals or around the anus
• Itching that can be severe and may get worse at night
• Burning or pain, especially during urination or intercourse
• Skin that tears or splits easily, sometimes with bleeding or bruising
• Blisters or raw areas, especially if scratched
• In men, difficulty pulling back the foreskin

Symptoms in children

• Itching and soreness around the genitals or anus
• Constipation because the child may avoid going to the toilet due to pain
• Difficulty urinating or a weak stream
• White patches that parents may notice during nappy changes or bathing

Symptoms in older adults

• Symptoms much the same, but skin is often thinner and more fragile with age
• A higher risk of tearing or bruising with minor friction
• Long-standing itching may have already caused scarring before diagnosis

Causes

Main causes

• The exact cause is unknown, but it is thought to involve an overactive immune system that attacks the skin.
• It may have a genetic link, as it can run in families.
• Hormonal changes may play a role, especially in women around menopause.
• It is not caused by poor hygiene, alcohol, smoking, or sexual activity.

Risk factors

• Being female – women are affected much more often than men
• Being past menopause, although it can happen at any age
• Having another autoimmune condition, such as thyroid disease, vitiligo, or alopecia areata
• A family history of lichen sclerosus or other autoimmune disorders

When to see a doctor

See a doctor urgently if:

• If you see spreading redness, warmth, or swelling that suggests an infection
• If you have an open sore that is weeping or becoming more painful
• If you are unable to urinate or have complete blockage of the bowel

Book a routine appointment if:

• If you have any persistent itching, soreness, or white patches on the genitals or anus
• If you have pain during urination or sexual intercourse that is new or ongoing
• If you notice skin that tears easily or blisters without an obvious cause
• If a child has itchy sore skin in the nappy area that does not improve with nappy cream

Diagnosis

A doctor can usually diagnose lichen sclerosus by listening to your symptoms and examining the affected skin. In some cases, they may refer you to a specialist skin doctor for a closer look.

Tests that may be done

• A physical examination of the affected area is the main test.
• Sometimes a small sample of skin (a biopsy) is taken to confirm the diagnosis.
• Blood tests are not usually needed, but may be done if an autoimmune condition is suspected.

What to expect at your appointment

The doctor will ask about your symptoms, when they started, and whether you have any other medical conditions. The examination should be quick and gentle. You can ask for a chaperone to be present if you prefer.

Treatment

Treatment focuses on calming the inflammation, relieving itching, and preventing scarring. With the right treatment, most people get good relief. It may take a few weeks to notice improvement, and sometimes the condition returns, so ongoing care is important.

Self-care at home

• Wash with plain water or a soap substitute, and pat the area dry gently.
• Wear loose-fitting cotton underwear and avoid tight trousers or leggings.
• Avoid scented soaps, bubble bath, and scented wipes.
• Use a gentle, fragrance-free moisturiser or barrier cream on the area if your doctor advises it.
• Avoid scratching – keep fingernails short and try cool compresses if itching is intense.
• For discomfort during intercourse, use a water-based lubricant.

Medical treatments

Doctors commonly prescribe a topical steroid cream or ointment to reduce inflammation. You apply a small amount to the affected skin for a set period, usually a few weeks, then reduce how often you use it. The strength of the steroid will be matched to your symptoms. For severe or stubborn cases, other anti-inflammatory medicines may be offered, but these are less common.

When is surgery considered?

Surgery is rarely needed. It may be considered if scarring has caused the foreskin to become too tight, the vaginal opening to narrow, or if there is an area suspicious of skin cancer. In children, circumcision sometimes helps when severe problems happen.

Living with this condition

Lichen sclerosus is a chronic condition, but most people manage it well with a simple daily routine. Keep the area clean and dry, use your prescribed treatment as directed, and avoid irritants. You may need check-ups every few months at first, and then once a year.

Lifestyle tips

• Choose soft, breathable fabrics and avoid tight clothing.
• Avoid activities that put prolonged pressure on the area, like long bike rides, unless comfortable.
• Use gentle, unscented products for washing and laundry.
• If swimming, change out of wet swimming costume as soon as possible.

Diet and exercise

There is no specific diet that treats lichen sclerosus. Eating a balanced diet and staying active help support your overall health and immune system. Regular gentle exercise, like walking or swimming, is fine – just shower soon after and dry well.

Mental health and emotional wellbeing

Living with lichen sclerosus can affect self-esteem, body image, and intimate relationships. Feelings of embarrassment or worry are normal. Talk to your doctor about any emotional distress – they can suggest counselling or support groups. Remember you are not alone, and seeking help is a sign of strength.

Prevention

Lichen sclerosus cannot be prevented because it is likely an autoimmune condition. However, early diagnosis and regular treatment can prevent most of the serious complications associated with it.

Screening programmes

If you have lichen sclerosus, your doctor may suggest regular check-ups to monitor the skin. Most people do not need intensive screening, but there is a small risk of developing skin cancer in affected areas, so staying in touch with your doctor is wise.

Complications

If left untreated

• Permanent scarring of the skin
• Fusion of the labia in women or narrowing of the vaginal opening
• Tightening of the foreskin in men, leading to difficulty urinating
• Chronic pain and discomfort
• Small but real increased risk of skin cancer in the affected area

Long-term outlook

With proper treatment, most people get significant relief from symptoms and can avoid serious complications. Lichen sclerosus is a long-term condition, but it is highly manageable. Regular follow-up and honest communication with your doctor give you the best chance of staying comfortable and well.
