About guttate morphea (sclerosus)

What is guttate morphea (sclerosus)?

Lichen sclerosus is a chronic skin disorder that most commonly affects post-menopausal women. However, it is sometimes identified among pre-menopausal women, and, even more rarely, among males. When found in males, the disease is known as balanitis xerotica obliterans.

Lichen sclerosus is characterized by skin changes of the external genitalia (i.e., vulva, head of the penis), although other parts of the body may also be affected. Intense itching often accompanies attacks of lichen sclerosus. The disorder is not contagious nor is it a sexually transmitted disease. In the recent past, a genetic component for lichen sclerosus has been recognized. In addition, many clinical researchers believe that it is a disorder of the immunological system. The understanding of the causes of this disorder is still incomplete. Lichen sclerosus can develop concurrently with other conditions.

What are the symptoms for guttate morphea (sclerosus)?

Morphea affects the skin and underlying tissue and sometimes bone. The condition generally lasts several years and then improves or at times disappears by itself. It may leave scars or areas of darkened or discolored skin. It is possible for morphea to recur.

What are the causes for guttate morphea (sclerosus)?

he cause of morphea is unknown. It may be caused by an unusual reaction of your immune system. In people at increased risk of morphea, it could be triggered by injury to the affected area, medications, chemical toxins, an infection or radiation therapy.

The condition isn't contagious.

What are the treatments for guttate morphea (sclerosus)?

Morphea usually lasts several years and then goes away without treatment. It may leave scars or areas of darkened or discolored skin. Until your condition clears up, you may want to pursue treatment that helps control your signs and symptoms.

Treatment options vary depending on the extent of your condition and how it's affecting your life. They include:

  • Medicated creams. Your doctor may prescribe a vitamin D cream, such as calcipotriene, to help soften the skin patches. Skin generally begins to improve during the first months of treatment. Possible side effects include burning, stinging and a rash.

    Or your doctor may prescribe a corticosteroid cream to reduce inflammation. When used for a long time, these creams may thin the skin.

  • Light therapy. For severe or widespread morphea, treatment may include the use of ultraviolet light (phototherapy).
  • Oral medications. For severe or widespread morphea, your doctor may prescribe an immunosuppressive medication, such as oral methotrexate (Trexall), corticosteroid pills or both. Or your doctor may suggest hydroxychloroquine (Plaquenil) or mycophenolate mofetil. Each of these drugs has potential side effects. Talk with your doctor about a drug's risks and benefits before using it.
  • Physical therapy. If the condition affects your joints, physical therapy might preserve your range of motion.

What are the risk factors for guttate morphea (sclerosus)?

Certain factors may affect your risk of developing morphea, including:

  • Being white and female. Morphea is most common in white females.
  • Age. The condition can affect people at any age. It usually appears between the ages of 2 and 14 or in the mid-40s.
  • A family history of morphea. This condition can run in families. People with morphea are more likely to have a family history of morphea and other autoimmune diseases.
