Lichen sclerosus is a chronic skin condition that primarily affects the genital and anal areas, although it can occur on other parts of the body. It is characterized by white patches of skin that may become thin, fragile, and itchy. The exact cause is unknown, but it is believed to involve an autoimmune response, where the body's immune system mistakenly attacks healthy skin. This condition can affect individuals of any age but is most common in postmenopausal women. Treatment options include topical corticosteroids to reduce inflammation and manage symptoms. Early diagnosis and management are important to prevent complications, such as scarring or discomfort during sexual activity.
