Pityriasis rosea is a self-limiting, salmon-colored patch that is followed by a spreading rash. The lesions are 1-2 cm in diameter, and are firmly attached at their borders and loose in the center, which gives them a cigarette-paper appearance. They last from 4-12 weeks, occurring more often in spring and fall, and usually in children and young adults.
