Lichen sclerosus is a chronic, non-contagious skin condition of the vulva (vulvar dermatosis). Typical features are white, parchment-like skin changes at the vaginal entrance and perineum, often accompanied by intense, chronic itching, burning and small tears. Untreated, it can lead to scarring and a slightly increased risk of vulvar cancer.
Many women live with symptoms for years before diagnosis – out of embarrassment, lack of awareness, or because symptoms were dismissed as 'normal'. You do not have to live with these symptoms: early, guideline-based treatment can significantly relieve itching and burning and largely prevent long-term skin changes.
At the practice of Dr. med. Anna M. Wagner at Spalenvorstadt 3 in Basel, assessment is discreet and woman-to-woman – for patients from Basel, Baselland and northwestern Switzerland. Together we develop a long-term treatment strategy with clear follow-up checks.
Key facts
At a glance.
- Lichen sclerosus is not curable, but very well treatable.
- The condition is not contagious and not caused by poor hygiene.
- Standard therapy is a high-potency cortisone cream (e.g. clobetasol).
- CO₂ laser is a complementary option in selected cases – not a miracle cure and not a replacement for cortisone.
- Without treatment, scarring (e.g. fusion of the labia minora, clitoral phimosis) and a slightly increased risk of vulvar cancer (approx. 4–5%) may occur.
- Regular follow-up checks are essential – even during symptom-free phases.
Causes
Background and risk factors.
The exact cause is not fully understood. Autoimmune processes, genetic predisposition and hormonal influences likely play a role together. Lichen sclerosus is neither contagious nor caused by poor hygiene or sexual activity – an important point, as many patients feel unnecessarily guilty.
Risk factors
- Female sex (women affected significantly more often)
- Peri- and postmenopause – peak incidence
- Autoimmune diseases (thyroid, vitiligo, alopecia areata) in personal or family history
- Genetic predisposition
- Can occur at any age, including in girls before puberty
Frequency
Lichen sclerosus is estimated to affect 1 in 70 to 1 in 300 women. The number of undiagnosed cases is high, as the condition is often diagnosed late.
Symptoms & findings
How does it present?
Typical symptoms
- Chronic itching in the vulvar area – often worse at night
- Burning and a raw sensation
- White, parchment-like skin changes at the vaginal entrance and perineum
- Pain during intercourse (dyspareunia)
- Small skin tears (fissures), bleeding with minor strain
- Uncertainty and distress in daily life
Common incidental findings
- Fusion of the labia minora
- Clitoral phimosis (clitoris no longer visible)
- Narrowing of the vaginal entrance
- Pain on urination
When is it detected?
Diagnosis is often made only after years of symptoms. Anyone noticing white skin changes, chronic itching or pain in the vulvar area should seek gynaecological assessment early – the earlier treatment begins, the better scarring can be prevented.
Diagnostics
How the diagnosis is made.
Diagnosis is usually made clinically by visual inspection – supplemented by vulvoscopy with magnified assessment. For atypical areas, treatment-resistant sites, or suspicion of cell changes, a small punch biopsy is taken under local anaesthesia.
Examinations
- Detailed history: symptoms, course, prior conditions (especially autoimmune)
- Clinical examination of the entire vulva and perianal region
- Vulvoscopy / colposcopy
- Punch biopsy of atypical or treatment-resistant areas
- If needed: assessment of accompanying autoimmune diseases
What do the findings mean?
Typical clinical signs are white, parchment-like skin areas, fissures, and loss of anatomical structure (clitoral phimosis, fusion of the labia). The goal is to reliably distinguish lichen sclerosus from other vulvar dermatoses (e.g. lichen planus, eczema, vulvovaginal atrophy) and from vulvar cell changes (VIN).
Treatment
Possible approach.
Watchful waiting
Basic care
mild, soap-free cleansing with lukewarm water, consistent use of rich emollients, avoidance of perfumed products and harsh cleansers. Cotton underwear, no panty liners in daily use. These measures do not replace cortisone therapy but support it effectively.
Medication
Standard therapy is high-potency topical corticosteroids (e.g. clobetasol) following a clear step-down regimen: initially daily, then tapering, and long-term maintenance therapy 1–2 times per week. Used correctly, they reliably relieve itching and prevent scarring and vulvar cancer. Second-line therapy – e.g. for insufficient response, cortisone intolerance, or during cortisone breaks – includes topical calcineurin inhibitors (tacrolimus ointment, off-label). During and after menopause, local oestrogen therapy can be a useful addition if vulvovaginal atrophy is also present.
Surgery
According to current guidelines, CO₂ laser is not used as a replacement for cortisone but as a complementary option in selected cases – for example, with insufficient response to consistent cortisone therapy or with pronounced skin changes. It is not a causal or permanent cure. Surgical procedures (e.g. releasing clitoral phimosis or a fused vaginal entrance) are performed only for relevant scarring and always in combination with continued medical therapy.
Prevention
What you can do yourself.
- Consistent maintenance therapy with cortisone cream – even during symptom-free phases
- Regular gynaecological follow-up checks (usually 1–2 times per year)
- Mild, soap-free intimate care, avoidance of perfumed products
- Cotton underwear, no permanent panty liners
- Self-inspection with a hand mirror – promptly report new white, thickened or sore areas
- Early presentation for symptoms – don't wait
