Lichen simplex chronicus on the back
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 that may develop increased pigmentation (hyperpigmentation).
