How is lichen simplex chronicus treated?

LSC is a self-perpetuating dermatosis, and it will persist until the initiating stimulus is eliminated. Interruption of the “itch-scratch cycle” is requisite to resolution. A short course of medium- or high-potency topical corticosteroids is typically employed. Covering the plaque is often important, as this acts as a physical barrier to continued frictional trauma and also acts as an occlusive adjunct for the topical preparation. Patients who express insight into the cause of their condition fare better. Resultant postinflammatory dyspigmentation may last for years, even after the changes of lichenification have resolved.
