Pityriasis Rosea

Pityriasis Rosea

What Is It?
Pityriasis rosea is a relatively common inflammatory skin disorder. It shows up as rose or salmon-colored, round to oval, slightly raised, scaling patches. Typically, it begins with a single original lesion called the "herald patch" which is larger. The herald patch is followed by other smaller rashes mainly on the trunk and neck following in a christmas tree-like pattern. It can cause some itching.

What Causes It?
The cause of pityriasis rosea is currently unknown, but recent research suggests it may be virus-related. It usually lasts six to twelve weeks and often clears up naturally. This skin condition affects mainly older children and young adults and is not contagious.

What Can Be Done?
Itching can be treated with antihistamines or topical steroids. A mild skin care routine such as a Cetaphil cleanser and moisturizing lotion are helpful for the dry scaling that occurs. Ultraviolet light therapy (UVB) or sunlight exposure appears to speed the healing process.
