Lichen Simplex Chronicus

Neurodermatitis

Overview

Lichen simplex chronicus (neurodermatitis) is a chronic skin condition caused by repeated scratching or rubbing of the same area of skin. This creates a self-perpetuating itch-scratch cycle that leads to thickened, leathery, darkened patches of skin. Breaking the itch-scratch cycle is essential for treatment.

Key Symptoms

• Thickened, leathery patch of skin (lichenification)
• Intense itching, often worse at night or during stress
• Skin may appear darker or reddish compared to surrounding skin
• Accentuated skin lines and markings in the affected area
• Well-defined borders of the affected patch
• Excoriations (scratch marks) may be visible

Affected Areas

Back of neck, Ankles, Wrists, Forearms, Genital area, Scalp

Care Instructions

1. Break the itch-scratch cycle — this is the most important step.
2. Apply potent topical corticosteroids to reduce itching and inflammation.
3. Keep the area moisturized with fragrance-free emollients.
4. Cover the area with bandages or clothing to prevent unconscious scratching.
5. Manage stress, which often triggers or worsens itching.
6. Consider antihistamines at bedtime to reduce nighttime scratching.
