What is Lichen Sclerosus? Symptoms, Causes, & Treatment

Lichen sclerosus is a chronic skin condition that causes white, patchy areas of thin skin, most commonly around the genital and anal areas. While it can affect anyone, it happens more often in women after menopause and occasionally in children.

This condition isn't contagious and you can't catch it from someone else. Think of it as your immune system mistakenly targeting healthy skin cells, which leads to inflammation and changes in the skin's appearance and texture over time.

What are the symptoms of lichen sclerosus?

The most noticeable sign is usually white, shiny patches of skin that may look wrinkled or crinkled like tissue paper. These patches often feel different from your normal skin and can be quite tender to touch.

You might notice several symptoms that can range from mild to more bothersome:

• White, shiny patches of skin that may appear wrinkled or smooth
• Itching that can be intense, especially at night
• Pain or discomfort during urination or bowel movements
• Painful intercourse in women
• Bleeding or tearing of the skin, even with gentle touch
• Skin that bruises easily in affected areas
• Scarring that can change the shape of the genital area over time

In some cases, you might experience less common symptoms like small bumps or blisters on the affected skin. The symptoms can come and go, with some people having flare-ups followed by periods where symptoms improve.

What are the types of lichen sclerosus?

Lichen sclerosus is generally classified by where it appears on your body. The genital type affects the vulva in women and the penis in men, while the extragenital type can appear anywhere else on your body.

Genital lichen sclerosus is the most common form. In women, it typically affects the vulva, including the area around the vaginal opening and sometimes extending to the anal area. In men, it usually affects the head of the penis and foreskin.

Extragenital lichen sclerosus can appear on your shoulders, chest, wrists, or other areas of your body. This type is less common and often causes fewer symptoms than the genital form.

What causes lichen sclerosus?

The exact cause isn't fully understood, but researchers believe it involves your immune system mistakenly attacking healthy skin cells. This autoimmune response creates inflammation that leads to the characteristic skin changes you see.

Several factors may contribute to developing this condition:

• Autoimmune disorders like thyroid disease or diabetes
• Genetic factors, as it sometimes runs in families
• Hormonal changes, particularly low estrogen levels after menopause
• Previous skin injury or trauma to the affected area
• Certain infections, though this connection isn't fully proven

In rare cases, some people develop lichen sclerosus after experiencing physical trauma to the skin, such as from tight clothing or injuries. However, most people with this condition don't have any clear trigger that doctors can identify.

When to see a doctor for lichen sclerosus?

You should see a healthcare provider if you notice white patches of skin, especially in your genital area, or if you're experiencing persistent itching or pain. Early diagnosis and treatment can help prevent complications and improve your comfort.

Don't wait to seek medical attention if you experience bleeding, severe pain, or difficulty with urination or bowel movements. These symptoms could indicate that the condition is progressing or causing complications that need prompt treatment.

If you're having painful intercourse or notice changes in the shape or appearance of your genital area, it's important to discuss these concerns with your doctor. They can help determine if lichen sclerosus is the cause and recommend appropriate treatment options.

What are the risk factors for lichen sclerosus?

Certain factors can increase your likelihood of developing this condition. Being a postmenopausal woman is the most significant risk factor, as hormonal changes during this time may trigger the condition.

Other factors that may increase your risk include:

• Having other autoimmune conditions like vitiligo or alopecia areata
• Family history of lichen sclerosus or other autoimmune disorders
• Being uncircumcised (for men), as the condition often affects the foreskin
• Previous genital infections or trauma
• Certain genetic factors that researchers are still studying

Children can also develop lichen sclerosus, though it's less common. In rare cases, the condition may improve on its own as children reach puberty, but this isn't something you should count on without proper medical care.

What are the possible complications of lichen sclerosus?

Without proper treatment, lichen sclerosus can lead to scarring that may cause functional problems. The scarring can narrow the vaginal opening in women or cause the foreskin to tighten in men, making daily activities uncomfortable.

Potential complications you should be aware of include:

• Scarring that changes the shape of genital structures
• Narrowing of the vaginal or urethral opening
• Painful intercourse that affects relationships and quality of life
• Difficulty with urination or bowel movements
• Increased risk of skin infections due to scratching
• Emotional distress from pain and appearance changes

In very rare cases, long-standing lichen sclerosus may slightly increase the risk of developing skin cancer in the affected area. This is why regular monitoring by your healthcare provider is important, especially if you've had the condition for many years.

How can lichen sclerosus be prevented?

Unfortunately, there's no known way to prevent lichen sclerosus since its exact cause isn't fully understood. However, you can take steps to avoid factors that might trigger flare-ups or worsen existing symptoms.

Gentle skin care can help minimize irritation. Use mild, fragrance-free soaps and avoid harsh chemicals or perfumed products in the genital area. Cotton underwear and loose-fitting clothing can reduce friction and irritation.

If you have other autoimmune conditions, working with your healthcare provider to manage them well might help reduce your overall risk. Regular check-ups can also help catch any changes early if you do develop the condition.

How is lichen sclerosus diagnosed?

Your doctor can often diagnose lichen sclerosus by examining the affected skin and asking about your symptoms. The white, shiny appearance of the patches is quite distinctive and helps healthcare providers identify the condition.

Sometimes your doctor might recommend a skin biopsy to confirm the diagnosis. This involves taking a small sample of affected skin to examine under a microscope, which can rule out other conditions that might look similar.

Your healthcare provider will also ask about any other symptoms you're experiencing and may check for other autoimmune conditions. Blood tests aren't typically needed to diagnose lichen sclerosus, but they might be helpful if your doctor suspects other related conditions.

What is the treatment for lichen sclerosus?

The main treatment is prescription topical corticosteroid creams or ointments, which help reduce inflammation and can significantly improve symptoms. Your doctor will likely prescribe a potent steroid cream that you'll apply to the affected areas regularly.

Treatment typically involves using the prescribed medication daily for several weeks, then reducing to a maintenance schedule. Many people see improvement in itching and pain within a few weeks, though it may take longer for the skin appearance to change.

Other treatment options your doctor might consider include:

• Topical calcineurin inhibitors like tacrolimus or pimecrolimus
• Hormone replacement therapy for postmenopausal women
• Phototherapy (light therapy) in some cases
• Surgery for severe scarring or complications
• Newer treatments like platelet-rich plasma therapy

In rare cases where conservative treatments don't work, your doctor might recommend surgical options. These could include procedures to remove scar tissue or reconstruct affected areas, though surgery is typically reserved for severe cases.

How to manage lichen sclerosus at home?

Good skin care can help manage your symptoms and prevent flare-ups. Keep the affected areas clean and dry, and avoid using harsh soaps or products with fragrances that might irritate your skin.

Gentle daily care includes washing with plain water or mild, fragrance-free soap and patting the area dry rather than rubbing. Applying a gentle, unscented moisturizer can help keep the skin supple and reduce irritation.

Wearing loose, cotton underwear and avoiding tight clothing can reduce friction and irritation. If you experience itching at night, keeping your fingernails short and wearing cotton gloves to bed can prevent scratching damage.

Stress management techniques like meditation or gentle exercise might help, as stress can sometimes worsen autoimmune conditions. Some people find that avoiding certain foods or activities that seem to trigger flare-ups can be helpful.

How should you prepare for your doctor appointment?

Before your appointment, write down all your symptoms and when they started. Include details about what makes them better or worse, and any treatments you've already tried.

Bring a list of all medications you're taking, including over-the-counter products and supplements. Also, note any other health conditions you have, especially autoimmune disorders or skin conditions.

Prepare questions you want to ask your doctor. You might want to know about treatment options, how long treatment takes to work, or what to expect long-term. Don't hesitate to ask about anything that concerns you.

If you feel nervous about the examination, remember that healthcare providers are experienced with these conditions and want to help you feel comfortable. You can ask for a same-gender provider if that makes you more comfortable.

What's the key takeaway about lichen sclerosus?

Lichen sclerosus is a manageable condition that responds well to treatment when caught early. While it can cause uncomfortable symptoms, proper medical care can significantly improve your quality of life and prevent complications.

The most important thing to remember is that this condition requires ongoing management rather than a one-time cure. With consistent treatment and good skin care, most people can control their symptoms and maintain normal activities.

Don't let embarrassment prevent you from seeking help. Healthcare providers are familiar with this condition and have effective treatments available. The sooner you start treatment, the better your long-term outcomes are likely to be.
