Lichen simplex chronicus (LSC) is a localized area of chronic, thickened, inflamed skin. Patients with LSC might have a single or multiple plaques in the affected area. LSC occurs mostly in adults and in people with anxiety and/or obsessive-compulsive disorder. LSC usually affects a patient’s dominant side and common areas such as back of scalp/neck, scrotum or vulva, wrists and forearms, and lower legs.
What causes LSC?
LSC presents after a cycle of repetitive scratching and rubbing as the result of chronic, localized itch. The causes of itch can include:
Topical medications: Strong topical steroids can be prescribed for application on the affected areas until the LSC has resolved. Tar preparations, cooling creams, and moisturizers can also be applied to relieve symptoms.
Steroid injections: Your dermatologist can administer a steroid injection into the site of the LSC plaques to reduce symptoms of itch.
Oral medications: Oral antihistamines can be prescribed to help relieve symptoms of itch and promote better sleep.
LSC can be a very disruptive condition. If you are experiencing symptoms of LSC, consult with our dermatologists to treat your symptoms and the primary condition leading to LSC.
