Lichen sclerosus

Lichen sclerosus is a chronic skin condition that is characterized by the development of thin, white patches on the skin that may appear crinkled or shiny. Lichen sclerosus most commonly affects the genital area in women and the foreskin in men, but it can also occur on other parts of the body, such as the upper thighs, lower abdomen, and upper arms. The cause of lichen sclerosus is not fully understood, but it is thought to be the result of an autoimmune reaction in which the body's immune system mistakenly attacks the skin. Lichen sclerosus is not contagious and is not caused by poor hygiene.

Symptoms of lichen sclerosus may include the development of thin, white patches on the skin that may appear crinkled or shiny, itching, and pain or discomfort during sexual activity or urination. In severe cases, lichen sclerosus may cause scarring and changes in the color and texture of the skin.

Diagnosis of lichen sclerosus is usually made through a combination of a physical examination and a biopsy of affected skin. A biopsy involves the removal of a small sample of skin for laboratory analysis.


Treatment for lichen sclerosus may involve the use of medications, such as corticosteroids or calcineurin inhibitors, to reduce inflammation and control the immune system. Treatment may also involve the use of moisturizing creams and ointments to keep the skin hydrated and to reduce itching. In severe cases, treatment may also involve the use of immunosuppressive drugs or light therapy. It is important to follow the recommendations of a healthcare provider and to take medications as directed to control the symptoms of lichen sclerosus and prevent complications.
