What is Lichen Simplex Chronicus?

Lichen simplex chronicus can be identified by a noticeable thickening of the skin, which occurs in response to excessive rubbing and scratching.

The affected area is darker than the surrounding skin and is usually scaly. It has been described as having a “leathery” appearance. Typically, the back of the neck, wrists and ankles are most often affected.

Stress and tension may intensify the itch-scratch cycle to the point that rubbing and scratching become an automatic, unconscious response. It can feel very satisfying to scratch this area, which makes treatment difficult.
