Pityriasis rosea is an eruption that develops in children and young adults in the spring and fall. The cause is unknown, but it is often associated with a recent upper respiratory infection or flu. It first presents as a single, scaly pink plaque on the trunk, called a "herald patch." Days to weeks later, an eruption of rose-colored papules follows the lines of cleavage in a "Christmas tree" distribution. It typically resolves in 4-6 weeks.
