Lichen simplex chronicus
Lichen simplex chronicus is a skin disorder characterized by chronic itching and scratching. The constant scratching causes thick, leathery, brownish skin.Causes
This is a skin disorder characterized by a self-perpetuating scratch-itch cycle:
- It may begin with something that rubs, irritates, or scratches the skin, such as clothing.
- This causes the person to rub or scratch the affected area. Constant scratching causes the skin to thicken.
- The thickened skin itches, causing more scratching, causing more thickening.
It is common in children, who chronically scratch insect bites and other areas. It can also be common in mentally retarded children who have chronic repetitive movements.
