Lichen Sclerosus
Key Points
Lichen sclerosus can cause anogenital bruising, itching, or blistering early, and atrophy and scarring later. Consider the diagnosis with any persistent anogenital dermatosis. Treat with long-term, high-potency topical corticosteroids, close monitoring, and sexual and psychologic support. Risk of subsequent squamous cell carcinoma is increased.
