This is called a herald patch and may be up to 4 inches (10 centimeters) across. Then you may get smaller spots that sweep out from the middle of the body in a shape that looks like drooping pine-tree branches. The rash can be itchy.</p> <p>Pityriasis (pit-ih-RIE-uh-sis) rosea can happen at any age but is most common between the ages of 10 and 35. It tends to go away on its own within 10 weeks.</p> <p>Treatment may help relieve the symptoms.</p> <p>The rash persists for several weeks and heals without scarring. Medicated lotions may lessen itchiness and speed the disappearance of the rash. Often, though, no treatment is required. The condition is not contagious and seldom recurs.</p> <fig> <title>Pityriasis rosea (initial phase)</title> <desc> <p>Pityriasis rosea typically begins with a large, slightly raised, scaly patch called the herald patch.</p> </desc> <image href="https://assets.mayoclinic.org[damPath]" placement="inline"> <alt>Herald patch of pityriasis rosea </alt> </image> </fig> </section> </conbodydiv> </conbody> </hecsConcept> <hecsConcept contentType="http://ontology.mayo.edu/ContentCategories/Symptoms" policy="did:mcid:PDkv3FCzsA4FPiHVvT1zRc" reviewedOn="2022-10-11T05:00:00.000-05:00" workId="did:mcid:GDXREHqX6KVwVVK33HSPud:2026-10-07" xml:lang="en"> <title>symptoms pityriasis rosea consumer</title> <titlealts> <titleSimple> <ph keyref="titleSimple-symptoms">Symptoms</ph> </titleSimple> </titlealts> <conbody> <conbodydiv platform="richtext"> <section> <p>Pityriasis rosea typically begins with an oval, slightly raised, scaly patch — called the herald patch — on the face, back, chest or abdomen.
