What is Pityriasis Rosea?
Pityriasis Rosea is a rather common skin disease in which round or oval, scaling pink patches develop mainly on the trunk of the body, upper arms, and thighs. In many cases the eruption begins with a single scaling patch (commonly called the “herald patch”), followed 1 – 2 weeks later by development of the widespread rash. The herald patch resembles ringworm, and thus is often confused with it. Pityriasis Rosea most commonly occurs in older children and teenagers but can appear at any age. It often occurs in seasonal epidemics during the Spring and Fall, but may develop as an isolated case at any time. Pityriasis Rosea symptoms are treated by Dr. Green for patients in the DC, Virginia, and Maryland regions.

What causes Pityriasis Rosea?
The cause of Pityriasis Rosea is not known. Because of its tendency to occur in seasonal epidemics and because of its rather predictable course, it is thought to be caused by a viral infection. If the disease is contagious at all, it is only slightly so, since multiple cases occurring at the same time within families are seen only very rarely.

What is the natural course of Pityriasis Rosea?
Pityriasis Rosea lasts from 6 – 12 weeks and then disappears leaving no scars. Naturally, you should contact Dr. Green if your condition becomes much worse or if it does not seem to follow the pattern.

How is Pityriasis Rosea treated?
Treatment is for relief of symptoms only and does not alter the overall course of the disease. Sometimes the rash is itchy. In that case, a prescription anti-itch cream or lotion to be applied to the uncomfortable areas may be provided to patients.
