What are the treatment options for lichen simplex chronicus?

This condition develops when repeated rubbing or scratching makes an itchy patch thicker and more noticeable. Treatment therefore addresses both the inflamed skin and the habit or trigger that keeps irritation going. A clinician may look for eczema, contact irritation, dry skin, stress-related scratching or another source of itch. The affected area and its thickness help guide the choice of treatment.

A prescribed topical corticosteroid can reduce inflammation and itching during a planned course. For a stubborn, thick plaque, a clinician may consider a steroid injection into the skin. These treatments need individual instructions because steroid strength, duration and injection suitability vary by body site.

Use prescribed medicine exactly as directed and apply moisturiser to reduce dryness and friction. Keep nails short, cover the patch at night if scratching happens during sleep, and use a cool compress when an urge to scratch appears. Loose, breathable clothing can help when the patch is on the body. Avoid fragranced products or rough fabrics that make the area itchier.

Treatment is more effective when the original trigger is managed. Your clinician may recommend changing a skin-care product, treating an underlying rash or planning support for stress-related scratching. Improvement can take time because thickened skin does not flatten immediately after itching settles.

Arrange an assessment if an itchy thick patch persists, spreads, bleeds, becomes painful or fails to improve with a sensible skin-care routine. Seek prompt care for increasing warmth, swelling, pus, fever or rapidly worsening tenderness, which can signal infection. A new or changing patch may need examination to confirm the diagnosis before stronger treatment is used.

Ask what may be triggering the itch, which steroid strength is appropriate for the site, how long to use it, and whether an injection is suitable for a thickened plaque. You can also ask how to protect the area overnight and what signs mean the diagnosis or treatment should be reviewed.
