Lichen sclerosus (LS) is a chronic skin condition that causes thin, white, patchy skin, often affecting the genital and anal areas. It can lead to itching, pain, and scarring if untreated. While it is not contagious or cancerous, early diagnosis and treatment are key to managing symptoms and preventing complications.
Common symptoms
- Intense itching (most common symptom).
- Thin, fragile, or wrinkled skin (may tear or bleed easily).
- White patches on the vulva, anus, or surrounding skin.
- Pain during sex (dyspareunia) or burning during urination.
- Scarring: In severe cases, the vaginal opening may narrow (introital stenosis).
Causes & risk factors
- Autoimmune link: Often associated with thyroid disease, vitiligo, or alopecia.
- Hormonal factors: More common in postmenopausal women, but can affect all ages (including children).
- Genetic predisposition: Family history of LS or autoimmune conditions.
- Skin trauma: Scratching or friction may worsen symptoms.
Diagnosis
- Physical exam: To examine the affected skin.
- Biopsy: A small skin sample may be taken to confirm LS and rule out cancer.
Treatment options
Topical steroids
- Clobetasol propionate ointment: High-potency steroid to reduce inflammation and itching (applied daily, then tapered).
- Regular use: Prevents scarring and improves skin health.
Moisturizers & Emollients
- Petroleum jelly or coconut oil: Soothes dry, cracked skin.
Follow-up care
- Regular check-ups to monitor skin changes and adjust treatment.
eGynaecologist Advice
- You must seek urgent gynaecological consultation if you develop painful urination or difficulty emptying the bladder occurs and if you develop skin cracks, sores, or bleeding.
- Early treatment prevents scarring and complications, and consistent steroid use is safe and effective, while you should continue to use under instructions of your gynaecologist.
Frequently Asked Questions
Is lichen sclerosus linked to cancer?
Rarely. Untreated LS slightly increases vulvar cancer risk, but proper steroid use lowers this risk.
Can men or children get LS?
Yes. Men may develop LS on the penis (causing phimosis). Children often outgrow it with treatment.
Is it hereditary?
Not directly, but autoimmune conditions may run in families.
Can I have sex with LS?
Yes! Use water-based lubricants and topical steroids to manage symptoms. Communicate openly with your partner.
Will LS go away?
It is a chronic condition, but symptoms can be controlled with treatment.
