Lichen planus: This common skin disease often develops on the wrist.
Many people get lichen (LY-kin) planus (PLAN-us). This disease can develop on one or several parts of the body. It can appear on the skin or inside the mouth. Sometimes, it appears in both places. Lichen planus can even change the way a person’s fingernails or toenails look. It also can appear on the genitals or a person’s scalp. Lichen planus is not contagious. You cannot get this disease from someone else, and you cannot give it to anyone.
Lichen planus is not a type of cancer.
