Pityriasis rosea (PR) is a common, acute, or subacute self-limited papulosquamous skin disease. Approximately 1–2 % of new dermatological patients are affected by PR. PR affects mainly children, adolescents, and young adults. PR usually remits within 3–6 weeks. Viral etiology of PR is probable. Asymptomatic and mild cases may be left untreated. If itch is important, topical corticosteroids are indicated. Phototherapy (UVB or UVA1) may be useful in the treatment. High-dose oral acyclovir, if introduced early in the course of PR, may reduce the disease duration.
