Pityriasis Rosea is a rash commonly seen in children and adults. The rash classically starts with a larger spot called a “herald patch.” This first patch is often red, raised, and slightly scaly. A few days after the patch appears, many smaller spots will begin to appear, often in the shape of a Christmas tree. Although the rash may look concerning, it is not contagious and will go away within 4-10 weeks. Other symptoms can include headache, tiredness, fever, sore throat before the rash appears, but many people are asymptomatic. Although the exact cause of pityriasis rosea is unknown, it is thought to be caused by certain viruses.
Many times the rash is asymptomatic, but in some the rash can be quite itchy and cause discomfort. If the rash itches or continues for longer than 10 weeks, it is best to see a doctor so they can ensure the rash is properly diagnosed and prescribe medications to help with itching. Treatments for itch include steroids, and antihistamines. There is no cure for pityriasis rosea, and treatment is symptomatic. Pityriasis rosea doesn’t cause scarring, and usually does not recur.
