Lichen simplex chronicus (LSC) is thick leathery skin with exaggerated skin markings caused by sudden itching and excessive rubbing and scratching.[1] It generally results in small bumps, patches, scratch marks and scale.[1] It typically affects the neck, scalp, upper eyelids, ears, palms, soles, ankles, wrists, genital areas and bottom.[1] It often develops gradually and the scratching becomes a habit.[1]
