Pityriasis rosea is a rash that can occur at any age but is occurs most commonly in people between the ages of 10-35 years old. The rash can last from several weeks to several months. Usually there are no permanent marks as a result of this disease, although some darker skinned persons may develop long-lasting flat brown spots that eventually fade. The condition often begins as a large single pink patch on the chest or back. This patch may be scaly and is called a “herald” or “mother” patch. Often the person with this patch will think it is a ringworm and will apply creams that will not help since the rash is not caused by a fungus. Hundreds of patches may appear on the body within a week or two. About half the patients will have some itching, especially when they become overheated. The cause is unknown and the rash is not contagious.
Treatment: External or internal medications for itching may be prescribed. Soothing medicated lotions and lubricants may also be prescribed. Cooler baths and showers may be recommended as well as strenuous activity. Some cases may not need to be treated but if you feel you may have this rash, seek help from your dermatology professional.
