Pityriasis Skin Rashes
You may never have heard the term before, but pityriasis is a common skin disease that generally appears as small, oval-shaped rashes under the skin. These rashes can differ in appearance, but are usually a pale red color for those with light skin, and are most commonly experienced by teenagers and young adults. The disease is often misdiagnosed as ringworm.
Pityriasis occurs in a distinctive pattern. A single rash usually occurs first (referred to as the “herald patch”), which is then followed within a few weeks by a clusters of new patches that typically form a pattern resembling the outline of an evergreen tree. Thankfully, the rashes usually heal on their own within about 6 weeks, although they can occasionally last for several months.
Pityriasis has two forms. In the milder pityriasis rosea form, the rashes do not exhibit much itchiness or pain and are mainly just a superficial annoyance. However, in the case of pityriasis lichenoides, there may be considerable itchiness and scaling. Occasionally other symptoms such as lack of energy or aches and pains may occur. For those with more severe symptoms, it’s recommended that the patient undergoes medical tests, as pityriasis lichenoides may suggest one has an autoimmune disorder such as HIV.
The cause of pityriasis is unknown, but thought to be viral. You’ll want to keep your immune system in top shape by making sure your daily vitamin intake is adequate. While pityriasis will generally heal on its own, over-exposure to high temperatures may make the condition worsen or last longer. To best speed recovery, you’ll want to avoid excess sun exposure or taking long, hot showers.
