In brief: Pityriasis Rosea

Pityriasis rosea (also known as pityriasis rosea giber) is a skin rash.
It is benign but may inflict substantial discomfort in certain cases.Classically, it begins with a single "herald patch" lesion, followed in 1 or 2 weeks by a generalized body rash lasting up to 12 weeks, however usually around 6 - 8. The cause of pityriasis rosea is not certain, but believed to be caused by a virus.
