Advanced lichen sclerosus et atrophicus (LSA) on the skin of the glans penis. The skin is scar-coloured, light, glossy, thin and fragile. Small petechiae are typical. Pruritus may occur, albeit more frequently in the early stages of the disease. The risk of squamous cell neoplasms is slightly increased, making follow-up necessary. Light, slightly glossy patches or blotches may occasionally be seen elsewhere on the skin. Treatment includes potent topical corticosteroids and tacrolimus cream.
