What causes lichen sclerosus in young girls?
The exact cause of lichen sclerosus in young girls is unknown, but it is thought to involve immune system factors, genetic predisposition, and possibly hormonal changes. It is not caused by infection or poor hygiene.
Detailed Medical Explanation
Research suggests that lichen sclerosus may be triggered by a combination of immune-mediated mechanisms, genetic factors, and skin trauma or irritation. Prepubertal girls may be more susceptible due to low oestrogen levels. There is no link with sexual abuse, and the condition is not contagious. For more, see the NHS and British Association of Dermatologists.
Clinical Context
Understanding the cause can help families and reduce stigma. Our clinic supports parents with education and sensitive care: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Current evidence points to an autoimmune and genetic basis, but further research is ongoing. National guidelines are available at BAD.
