About Pityriasis Rosea

What is It?

Pityriasis rosea is a common skin disease and appears as a rash that can last from several weeks to several months. It most often develops in the spring and the fall, and is more prevalent in adolescents or young adults, and is uncommon in those over 60. Usually there are no permanent marks as a result of this disease, although some darker-skinned persons may develop long-lasting flat brown spots.

The skin rash follows a very distinctive pattern and varies from person to person. In most cases, a single, isolated oval scaly patch (the "herald patch") appears on the body, particularly upper part of the body, but again every individual reacts differently. This is often mistaken for ringworm or eczema. More pink patches can occur on different parts of the body, but rarely on the face.

What Causes It?

There is no proven cause for this skin disease. It's not caused by a fungus or bacterial infection or any known type of allergic reaction and is not a sign of any type of internal disease. It is neither contagious nor sexually transmitted, so there is no reason to avoid close or intimate contact when someone has it If you suspect that you might have this skin disease, its best to make an appointment with your dermatologist who will be able to diagnose your condition upon an examination.

It is thought that it may be caused by a virus since the rash resembles certain viral illnesses, and occasionally a person feels slightly ill for a short while just before the rash appears. Pityriasis rosea does not seem to spread from person to person and it usually occurs only once in a lifetime.

Common Treatments

Your dermatologist will be able to diagnose it by sight. For confirmation, they may order a blood test, a scraping or a biopsy. The only reason for tests is to rule out other types of skin problems, like eczema, ringworm, or psoriasis. Usually pityriasis rosea clears up in a few weeks. If you are experiencing itching, your doctor may recommend topical medications such as calamine lotion, an antihistamine or even a steroid cream.

All medications will depend on your diagnosis, which is why is important to book your appointment today with your dermatologist so that you will be on your road to recovery soon. After all Healthy Skin is our Passion.
