Pityriasis Rosea is a common skin rash in people 10-35 years old. Often patients will have a pink to bright red "herald patch" about one to two inches in diameter one to two weeks before the rest of the rash. The rest of the lesions are roughly oval, pink in color with a scaliness on top. Most of the spots will be on the body but they can occur on arms and legs as well. Itching may vary from minimal to severe. The rash is thought to be caused by an immune system reaction to a virus. It is not contagious. There is no specific treatment for this rash but it will go away by itself in two to six weeks. Sometimes ultraviolet sunlight may help the itching (don't get burned). If the itching is bothersome, your provider can give you medication to help until it goes away.
