Lichen Sclerosus & Vulval Health
More Than "Just an Itch"
When it comes to women’s health, the vulva is perhaps the most neglected area of discussion. Many women suffer for months, or even years, with persistent itching, burning, or soreness, assuming they are experiencing a recurring bout of thrush or a reaction to a new soap. However, when these symptoms become chronic, they are often a sign of an underlying inflammatory skin condition. The most common and significant of these is Lichen Sclerosus (LS).
As a gynaecologist, I meet many women who are exhausted by the physical discomfort and the emotional toll of vulval symptoms. My goal is to provide a safe, discreet environment where we can move past the embarrassment and secure a diagnosis that allows you to reclaim your comfort and protect your long-term skin health.
What is Lichen Sclerosus?
Lichen Sclerosus is a chronic, inflammatory skin condition that primarily affects the genital and anal areas (though it can occasionally appear on other parts of the body). It is not an infection, it is not contagious, and it is not a result of poor hygiene. While its exact cause is still being researched, it is widely believed to be an autoimmune condition, where the body’s immune system mistakenly attacks its own skin cells.
If left untreated, the chronic inflammation causes the skin to become thin, white, and crinkly (often described as "parchment-like" or "cigarette paper" skin). Over time, this can lead to permanent changes in the anatomy of the vulva, including scarring that can cover the clitoris or narrow the vaginal opening.
Identifying the Symptoms
The primary symptom of Lichen Sclerosus is intense itching, which is often worse at night. This can be so severe that it disrupts sleep. Other symptoms include:
White Patches: Smooth, white spots that can grow into larger, thickened patches.
Fragile Skin: The skin becomes very delicate and may split or tear easily, even during normal activities or gentle wiping.
Soreness and Burning: A persistent stinging sensation, which can make urination or sexual intercourse painful.
Bruising: Small purple or red spots under the skin caused by minor trauma to the fragile tissue.
Why a Specialist Diagnosis is Essential
It is estimated that Lichen Sclerosus is significantly underdiagnosed. Many women use over-the-counter antifungal creams for years without relief. It is vital to see a specialist for any persistent vulval symptoms for two main reasons:
Preventing Scarring: Early and consistent treatment can stop the progression of the disease and prevent the loss of vulval architecture.
Malignancy Risk: While the vast majority of cases do not become cancerous, untreated Lichen Sclerosus carries an increased risk (approximately 4–5%) of developing vulval squamous cell carcinoma. Regular monitoring by a gynaecologist is the best way to catch any changes early.
The Diagnostic Approach
When we identify a cyst, we use several tools to assess its risk level:
Pelvic Ultrasound: This is the most effective way to see if a cyst is "simple" (filled only with fluid) or "complex" (containing solid areas or irregular features).
Serial Monitoring: For simple cysts, we often wait 6–8 weeks and repeat the ultrasound to see if the cyst has resolved.
Tumour Markers (CA-125): In certain cases, especially in post-menopausal women, we may use blood tests to help assess the risk of malignancy. It is important to note that CA-125 can also be raised by benign conditions like endometriosis or fibroids.
The Diagnostic Process
Diagnosis begins with a visual examination. In many cases, the appearance of the skin is classic enough for a clinical diagnosis. However, to be certain, I may perform a Vulval Biopsy. This is a quick procedure performed under local anaesthetic in my rooms. A tiny sample of skin (about 3mm) is taken and sent to a pathologist to confirm the diagnosis and rule out other conditions like Lichen Planus or vulval eczema.
Management: The Gold Standard
While there is no "cure" for Lichen Sclerosus, it is highly manageable with the right treatment plan.
Ultra-Potent Topical Steroids: The "gold standard" of treatment. When used correctly—starting with an intensive phase and moving to a maintenance "pulse" therapy—steroid ointments can put the disease into remission, heal the skin, and prevent future scarring.
Emollients: Using soap-free washes and thick barrier creams (like plain paraffin) to protect the skin from irritants like urine and sweat.
Lifestyle Adjustments: Wearing loose, cotton underwear, avoiding scented products, and using specialized lubricants for intimacy.
Frequently Asked Questions about Lichen Sclerosus
Q: Is Lichen Sclerosus a form of cancer?
A: No, it is an inflammatory skin condition. However, if it is not treated, the chronic inflammation can slightly increase the risk of vulval cancer. With regular treatment and monitoring, this risk is significantly reduced.
Q: Can I use over-the-counter thrush cream for the itch?
A: If you have Lichen Sclerosus, thrush creams will not work and may actually irritate the skin further. It is important to get a correct diagnosis before starting any treatment.
