Does lichen sclerosus cause white patches on skin?

Lichen sclerosus can make affected skin look pale or white, thin, crinkled, or shiny. It commonly involves the vulval or penile skin and the skin around the anus, although other sites can be affected. Itching, soreness, tiny cracks, or pain with urination or sex may occur.

A pale patch is not enough to identify the condition. Vitiligo, healed inflammation, irritation, fungal problems, and other disorders can also change skin colour. A clinician may examine the area carefully and sometimes take a small sample when the diagnosis or appearance is unusual.

Avoid fragranced washes, scrubbing, and tight clothing. Rinse gently, pat dry, and use a plain protective emollient if advised. Do not scratch or use over-the-counter steroid, antifungal, or lightening products without guidance, because sensitive genital skin can be harmed by the wrong treatment. Prescribed anti-inflammatory ointment can control symptoms and protect the skin.

Arrange a medical review for new white patches, persistent itching, cracking, bleeding, pain, or changes in the opening of the vagina, urethra, or foreskin. Seek prompt assessment for a sore, lump, ulcer, or area that does not heal. Ongoing follow-up helps monitor symptoms and any change that needs further investigation.

Ask whether the patch pattern fits Lichen Sclerosus, whether nearby skin needs examination, how to apply prescribed ointment, and which changes should trigger an earlier appointment.
