Lichen Sclerosus

What is lichen sclerosus?

Lichen sclerosus is a long-term problem of the skin. It mostly affects the genital and anal areas. Sometimes, lichen sclerosus appears on the upper body, breasts, and upper arms.

Who gets lichen sclerosus?

Lichen sclerosus appears in:

  • Women (often after menopause)
  • Men (uncommon)
  • Children (rare).

What are the symptoms?

Early in the disease, small white spots appear on the skin. The spots are usually shiny and smooth. Later, the spots grow into bigger patches. The skin on the patches becomes thin and crinkled. Then the skin tears easily, and bright red or purple bruises are common. Sometimes, the skin becomes scarred. If the disease is a mild case, there may be no symptoms.

Other symptoms are:

  • Itching (very common)
  • Discomfort or pain
  • Bleeding
  • Blisters.

What causes lichen sclerosus?

Doctors don't know the exact cause of lichen sclerosus. Some doctors think a too active immune system and hormone problems may play a role. It is also thought that people inherit the likelihood of getting the disease. Sometimes, lichen sclerosus appears on skin that has been damaged or scarred from some other previous injury.

Lichen sclerosus is not contagious (it can't be caught from another person).

How is it diagnosed?

Doctors can look at severe lichen sclerosus and know what it is. But usually, a doctor takes a small piece of the skin patch (biopsy) and looks at it under a microscope. This allows doctors to make sure that it is not a different disease.

Lichen Sclerosus

What is menopause?

Menopause is the absence of menstrual periods for 12 months. The menopausal transition starts with varying menstrual cycle length and ends with the final menstrual period. Perimenopause means "the time around menopause" and is often used to refer to the menopausal transitional period. It is not officially a medical term, but is sometimes used to explain certain aspects of the menopause transition in lay terms. Postmenopause is the entire period of time that comes after the last menstrual period.

Menopause is the time in a woman's life when the function of the ovaries ceases. The ovary, or female gonad, is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones such as estrogen. During each monthly menstrual cycle, an egg is released from one ovary. The egg...
