Pityriasis Rosea - Presentation
An upper respiratory tract infection precedes all symptoms. Then, a 2-10 cm herald patch, salmon pink colored with a collarette scale at the margin appears typically on the abdomen. (1) Secondary eruptions begin typically along the Langer (cleavage) lines after a few days to weeks which are similar to the herald patch and align in a "Christmas tree" appearance on the torso. (1,2) Patients, especially children, often experience mild to severe pruritis. (4)

Other associated symptoms like low-grade fever, nausea and headache are possible.

Atypical presentations have also been reported where the herald patch is either missing or confluent with other lesions.
