Pityriasis Rosea:
Teen information

Pityriasis rosea is a common rash that can affect children, teens, and adults. It tends to come on quickly, last for 1–2 months, and then fade. Pityriasis rosea is not itchy or painful, though some people are bothered by the appearance of the rash. The rash typically looks like oval-shaped, reddish or pinkish patches. It often starts as one large patch on the chest or back, and then many more oval-shaped patches appear. Some people experience the rash of pityriasis rosea in a "Christmas-tree" pattern, with the patches spanning from the center of the back that resemble the branches of a Christmas tree. There is no certain treatment for pityriasis rosea; the good news is that it is not contagious, it goes away on its own, and it rarely involves the face.
