Lichen simplex chronicus is an area of chronic, hyperpigmented, lichenified plaque. Lichen simplex chronicus, or neurodermatitis,is an area of localized, well-circumscribed lichenification (thickened skin) resulting from repeated rubbing, itching, and scratching of the skin. The condition occurs in both males and females, but is unusual in children. Symptoms of lichen simplex chronicus include dry, scaly patches, pigmentation, scratch marks, areas of leathery-appearing skin, and broken hairs. A doctor can diagnose lichen simplex chronicus by examining the area and by taking a skin biopsy or scraping. Treatment for lichen simplex chronicus includes topical steroids, steroid injections, coal tar preparations, moisturizers, cooling creams, and antihistamines.
