Picture of Pityriasis Rosea 1
Pityriasis rosea is a skin condition that most often occurs in those between the ages of 10 and 35. The condition is characterized by an itchy rash that appears on the chest or back. The first lesion that appears is called a "herald" patch. Within approximately the next week, smaller patches appear on the legs, arms, and torso. Heat tends to exacerbate the itching. Taking a lukewarm bath or shower instead of a hot one may help relieve symptoms. Topical medications can also provide relief from itching.
