Lichen simplex chronicus


Lichen simplex chronicus

Description, Causes and Risk Factors:

Alternative Name: Neurodermatitis.

Abbreviation: LSC.

LSC is a chronic inflammatory skin disease characterized by paroxysms of pruritus and the development of lichenoid changes of the skin. The disease occurs from repeated scratching or rubbing, either as a habit or in response to stress. There is no underlying dermatological disorder.

This condition tends to occur on the nape of the neck, the wrists, the elbows, the ankles, and the anogenital region. It may also spread to the limbs, the areas around the eyes and the sacrococcygeal region. It is more common in adults and is unrelated to season.

The cause of lichen simplex chronicus is unknown. This disorder may occur with:

    Eczema (atopic dermatitis).

  • Psoriasis.

  • Nervousness, anxiety, depression, and other psychological disorders.

The disease is more common in children, who chronically scratch insect bites and other areas. It can also be common in mentally retarded children who have chronic repetitive movements.

Symptoms:

    Skin itching.

  • Scaling of the skin.

  • Reddened skin.

  • Skin lesion, patch, or plaque.

Diagnosis:

The diagnosis is primarily based on the appearance of the skin and a history of chronic itching and scratching. A skin lesion biopsy may be needed to confirm the diagnosis.

Treatment:

The itching and inflammation may be treated with a lotion or steroid cream applied to the affected area of the skin. Peeling ointments, such as those containing salicylic acid, may be used on thickened lesions. Soaps or lotions containing coal tar may be recommended.

Other Treatment Options Include:

    Antihistamines to relieve the itching.

  • Corticosteroids creams.

  • Corticosteroid injections into the affected area to reduce itching and inflammation.

  • Occlusive dressing, which seals a wound completely, to prevent the person from scratching.

  • Sedatives and tranquilizers to reduce stress.

  • Antidepressants, if there is an emotional component to the condition.

  • Counseling, stress management, or behavior modification.

Side effects of treatment depend on the medication used. They may include drowsiness, dry mouth, and allergic reactions.
