Christmas Tree Rash
Christmas tree rash or pityriasis rosea is an itchy, scaly, and fine type of skin rash that typically appear as a single patch around the back, abdomen, or on the chest at first. The herald patch might spread as smaller patches to other areas of the neck, chest, and back. The rash sometimes forms a pattern on some areas of the body especially on the back that are similar to a Christmas tree. Pityriasis rosea typically goes away on its own in almost four to ten weeks, but it might last for months. The use of medicated topical lotions might reduce the spread and itchiness of the rash.
