Overview
Lichen simplex chronicus is also known as neurodermatitis. A minor itch may encourage scratching which increases the irritation, leading to more scratching. This ultimately results in a rough, scratched (excoriated), thickened skin surface which may develop increased pigmentation (hyperpigmentation) as seen here on the front part of the foot, just below the leg.
