Lichen simplex chronicus is also known as neurodermatitis or scratch dermatitis. It's caused by the itch-scratch cycle which, for many patients, is a neurological habit. As a patient responds to the itchiness with continuous scratching, the skin develops a leathery and scaly texture. Lichen simplex chronicus isn't contagious or dangerous and is found on the ankles, forearms, legs, and neck.
Lichen Simplex Chronicus affects women more than men and generally appears between age 30 and age 50. The exact cause is unknown but tends to have particular triggers, such as insect bites and stress. As scratching continues, the affected area may become discolored, thickened, and even itchier.
Breaking the itch-scratch cycle is important to complete treatment. Because the affected area generally has broken skin, a bacterial infection may develop, exacerbating the condition. Your dermatologist may use various treatment options for lichen simplex chronicus, including oral antihistamines and corticosteroids to reduce inflammation and provide itch relief.
Your dermatologist may suggest using topical creams and moisturizers to calm the affected skin and aid in its healing. Some patients use gloves, socks, and other coverings to break the itch-scratch cycle. This also allows topical treatments to deeply penetrate the skin without disturbance. Peeling ointments containing salicylic acid can help soften rough skin.
