Lichen Simplex Chronicus (LSC) Treatment in London

Understanding Lichen Simplex Chronicus

Lichen simplex chronicus (LSC) is a skin disorder that develops from repeated scratching or rubbing of the skin. The continuous trauma causes thickened, rough, and hyperpigmented plaques. It is also known as neurodermatitis, reflecting the strong link between psychological stress and skin changes. Although not life-threatening, it significantly impacts quality of life, often interfering with sleep and daily activities.

Causes and Risk Factors

LSC develops when a sensitive area of skin becomes itchy and scratching continues over time. Common causes and risk factors include:

• Underlying skin conditions: eczema, psoriasis, or dry skin
• Stress and anxiety: psychological factors can worsen itching
• Allergies or insect bites: trigger localised itching that becomes chronic
• Nerve irritation: neuropathic itch or spinal nerve injury
• Clothing friction: tight garments irritating the skin

Symptoms

• Intense, persistent itch (worse at night)
• Thickened, leathery plaques (lichenification)
• Darkened or lightened patches
• Increased skin markings (lichenification lines)
• Pain, burning, or soreness if skin cracks

Common Sites

LSC can occur anywhere but is most often seen on:

• Scalp and nape of the neck
• Shins and ankles
• Forearms and wrists
• Genital areas (vulva, scrotum, anus)

Lichen Simplex Chronicus Complications

Without treatment, LSC may cause:

• Thickened and permanently discoloured skin
• Secondary skin infections
• Emotional distress, depression, or anxiety
• Sexual difficulties when affecting genital skin

Lichen Simplex Chronicus Diagnosis

Diagnosis is clinical, based on examination and patient history. In some cases, a skin biopsy may be performed to exclude other conditions such as psoriasis, fungal infections, or precancerous lesions.

Lichen Simplex Chronicus Treatment Options

• Topical corticosteroids: reduce inflammation and itching.
• Emollients: restore skin barrier and reduce dryness.
• Antihistamines: control nighttime itching.
• Topical calcineurin inhibitors: useful for genital areas or steroid-sensitive skin.
• Behavioural therapy: breaking the itch–scratch cycle through mindfulness and habit-reversal.
• Treating underlying causes: managing eczema, stress, or allergies.

Living with Lichen Simplex Chronicus

Patients can manage LSC successfully with treatment and lifestyle changes. Avoiding irritants, wearing loose cotton clothing, and using emollients regularly helps prevent flare-ups. Stress management and psychological support are also crucial, since stress often exacerbates itching.
