What Is Lichen Sclerosus?

Lichen sclerosus is a chronic inflammatory skin condition that most commonly affects the vulva and perianal skin. It is thought to be autoimmune in origin and is unrelated to hygiene, sexually transmitted infections, or anything the patient has done wrong.

It can occur at any age, but is most common in postmenopausal women and in young girls. It also affects men (on the penis) as balanitis xerotica obliterans. Lichen sclerosus is not contagious.

Without treatment, lichen sclerosus tends to cause progressive thinning, whitening, fissuring, and scarring of the vulvar skin. Over many years, untreated disease carries a small but real risk of vulvar squamous cell carcinoma (~2–5%). Appropriate, ongoing treatment largely prevents these complications.

Symptoms

Common Symptoms

  • Vulvar itching — often intense, worse at night
  • Burning or soreness
  • Painful intercourse (dyspareunia)
  • Cracks or fissures with movement, intercourse, or bowel movements
  • Bruising or bleeding with minor friction

Skin Changes

  • White, thin, "cigarette paper" skin in a figure-8 pattern around the vulva and anus
  • Loss of labia minora or clitoral hood architecture
  • Narrowing of the vaginal opening
  • Sometimes involves perianal skin only

When to Seek Care

Any persistent vulvar itching, new lumps, non-healing ulcers, or skin color change warrants prompt evaluation — both to confirm the diagnosis and to rule out other conditions.

How Is It Diagnosed?

Diagnosis is most often made clinically, supported when needed by a small skin biopsy.

  • History — pattern and duration of itching, effect on intercourse, prior treatments
  • Vulvar exam — looking for the characteristic white, thin, atrophic changes and architectural loss
  • Vulvar biopsy — a small punch biopsy may be performed in the office to confirm the diagnosis, especially in unclear cases or if there is suspicion of cancer
  • Differentiating conditions — lichen planus, lichen simplex chronicus, atrophic vaginitis, candidiasis, and contact dermatitis

Treatment

The goals of treatment are to (1) control symptoms, (2) prevent scarring and architectural loss, and (3) reduce long-term cancer risk. Most patients improve dramatically with proper therapy.

1. Ultra-Potent Topical Corticosteroid — First-Line Therapy

High-potency topical corticosteroid — most commonly clobetasol propionate 0.05% ointment — is the standard of care. Used correctly, it is highly effective and very safe.

Typical Regimen

  • Induction: a pea-sized amount once daily at bedtime for 4–12 weeks
  • Taper: every other night, then 2–3 nights per week
  • Maintenance: 1–2 times per week long-term, in most patients
  • Flares: return to daily use for a short period, then taper

Tips for Success

  • Use a small amount — the skin does not need a lot
  • Apply to affected skin, including the perianal area if involved
  • Stay consistent — skipping maintenance is the most common reason for flares
  • Gentle skin care: fragrance-free, no douching, loose cotton underwear

2. Supportive Care

  • Emollients / barrier creams — petrolatum, zinc oxide, or similar to protect irritated skin
  • Avoid irritants — scented soaps, bubble baths, harsh cleansers, fragranced pads or wipes
  • Treat coexisting infection — yeast or bacterial infections can flare the condition
  • Topical vaginal estrogen — often added in postmenopausal women to address coexisting GSM (see benefits of topical estrogen)

3. Additional / Second-Line Therapies

  • Topical calcineurin inhibitors (tacrolimus, pimecrolimus) — steroid-sparing alternatives used in select cases
  • Pelvic floor physical therapy — for vaginismus or pelvic floor guarding
  • Vaginal dilators — for introital narrowing
  • Surgery — occasionally needed to correct scarring (e.g., fusion over the clitoris, introital narrowing that limits intercourse or catheterization)

Long-Term Monitoring

Because lichen sclerosus is chronic and carries a small long-term risk of vulvar cancer, regular follow-up is important:

  • Every 6–12 months — a focused vulvar skin exam
  • Sooner if there are new lumps, non-healing ulcers, persistent thickening, or bleeding
  • Self-exams — we will teach you how to check your own skin

Key Point

Staying on maintenance therapy — even if symptoms are gone — keeps the disease controlled and lowers the risk of complications and cancer. Stopping treatment is the main reason the disease progresses.

Frequently Asked Questions

Is lichen sclerosus contagious?

No. It is not sexually transmitted or infectious. It is considered autoimmune.

Does lichen sclerosus go away?

It is chronic but very treatable. With the right regimen, most patients feel better and live normally.

Is a high-potency steroid safe for long-term use?

Yes — when applied in small amounts to the correct area and properly tapered to maintenance, clobetasol is safe for long-term use and has an excellent track record.

Can it turn into cancer?

There is a small long-term risk of vulvar squamous cell carcinoma in long-standing untreated disease. Treatment plus surveillance dramatically reduces this risk.

Can I still have sex?

Yes — once symptoms are controlled. Topical steroids, lubricants, dilators, and pelvic floor PT can all help restore comfortable intercourse.

You Are Not Alone — and This Is Treatable
