Symptoms

By Mayo Clinic staff

Pityriasis rosea symptoms include:

  • Initial phase. Pityriasis rosea typically begins with a large, slightly raised, scaly patch — called the herald patch — on your back, chest or abdomen.
  • Progression. Smaller fine, scaly spots usually appear across your back, chest or abdomen in a pine-tree pattern a few days to a few weeks after the herald patch. Rarely, smaller spots may also appear on your arms, legs or face. The rash may itch.
  • Color. The rash of pityriasis rosea often is scaly and pink, but if you have darker skin, it may be gray, dark brown or even black.
  • Other signs and symptoms. About half the people who develop pityriasis rosea have signs or symptoms of an upper respiratory infection — such as a stuffy nose, sore throat, cough or congestion — just before the herald patch appears.
