Pityriasis rosea is a mild, but common, skin condition. Characterized by scaly, pink, inflamed skin, the condition can last from one to three months and usually leaves no lasting marks.
The cause of pityriasis rosea is not known, but it is commonly believed to be caused by a virus or bacteria. Some patients may have a cold before the rash. It is usually seen in children, adolescents, and young adults. Most people with the rash are 10 to 35 years of age.
The condition is more prevalent in spring and fall.
Pityriasis rosea usually starts with a pink or tan oval area (sometimes called a herald or mother patch) on the chest, stomach, or back. The main patch is usually followed (after a couple of weeks) by smaller pink or tan patches elsewhere on the body, usually the back, neck, arms, and legs. The scaly rash usually lasts between four to eight weeks and will disappear without treatment.
