Pityriasis rosea is a type of skin rash.[2] Classically, it begins with a single red and slightly scaly area known as a "herald patch".[2] This is then followed, days to weeks later, by a pink whole body rash.[3] It typically lasts less than three months and goes away without treatment.[3] Sometime a fever may occur before the start of the rash or itchiness may be present, but often there are few other symptoms
