## What is the difference between lichen sclerosus and lichen planus?

Here at Alloy, I can only answer part of that reliably.

Lichen sclerosus is an autoimmune inflammatory skin condition that often affects the vulva. In our materials, it’s described as causing white, thin, papery-looking skin, itching, scarring, and sometimes loss of the labia minora. It should be diagnosed carefully, often with a biopsy, because long-term inflammation can increase the risk of vulvar cancer. Treatment is usually ongoing, often with a topical steroid, and for people in menopause, local hormone treatment may also help keep the tissue healthier.

I don’t have information in the materials here on lichen planus, so I can’t give you a trustworthy side-by-side comparison with lichen sclerosus.

One useful detail from Dr. Rachel Rubin is that hormonal changes in menopause can sometimes make vulvar tissue look irritated or fragile, and that can be mistaken for lichen sclerosus, which is one reason a specialist exam and biopsy matter.
