Pityriasis rosea (pit-uh-RI-uh-sis RO-zee-uh) is a mild, common rash. It causes the skin to become scaly, pink, and inflamed. The rash can last from 1 to 3 months and usually leaves no lasting marks. This rash is not contagious.


Experts don’t know what causes pityriasis rosea. It is believed to be caused by a virus or bacteria. It is usually seen in children, adolescents, and young adults. Some children may have a cold before the rash. The rash is more common in spring and fall.


The rash usually starts with a large pink or tan oval area on the chest, stomach, or back. This patch (herald patch) is usually followed by smaller pink or tan patches elsewhere on the body. They usually show up on the back, neck, arms, and legs. The scaly rash usually begins to heal on its own in 4 to 6 weeks and will go away by 14 weeks.

Below are other common symptoms of pityriasis rosea. But each child may experience symptoms differently. Symptoms may include:

  • Fatigue
  • Aches
  • Itching

The symptoms of pityriasis rosea may look like other skin conditions or health problems. Always talk with your child’s healthcare provider for a diagnosis.


The rash is unique. Pityriasis rosea is usually diagnosed based on a health history and physical exam of your child. In addition, your child’s healthcare provider may order blood tests to rule out other conditions that might look like pityriasis rosea.


Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

The goal of treatment for pityriasis rosea is to relieve symptoms such as itching. The rash will resolve on its own. Treatment will be decided by your child’s healthcare provider based on how bad the rash is. Treatment may include:

  • Medicated lotions and creams
  • Medicines taken by mouth
  • Cool baths with or without oatmeal
  • Ultraviolet exposure
  • Cool compresses
