Pityriasis Rosea

Overview of Pityriasis Rosea

Pityriasis Rosea is a common, mild, self- limiting skin rash that resolves or disappears on its own after 6-8 weeks. The rash heals without scarring. This rash is 50% more common in women, more common in young adults and more common in spring or fall. 

Signs & Symptoms

  • An oval shaped rash, pink or “fawn” colored with scaly “collarets” around the border. The rash usually occurs at the natural folds of the back, chest and abdomen.
  • The rash can be preceded by one slightly larger spot (called a herald patch) 1-2 weeks before the other spots appear.
  • The rash can be mildly itchy. 


There is no known prevention. There are cases of other family members being affected but it is not considered contagious. 


If the rash is unusual or there is doubt about your diagnosis, your health care provider may perform lab tests or skin scrapings to determine the diagnosis.

Pityriasis Rosea requires no treatment. Sometimes topical steroids are used to reduce itchiness.
