Penyakit-penyakit Di Dunia : Pityriasis rosea

CAUSES, INCIDENCE AND RISK FACTORS

Pityriasis rosea is believed to be caused by a virus. It occurs most often in the fall and spring.

Although pityriasis rosea may occur in more than one person in a household at a time, it is not thought to spread from one person to another.

Pityriasis rosea is a common type of skin rash seen in young adults.

SYMPTOMS

Attacks most often last 4 - 8 weeks. Symptoms may disappear by 3 weeks or last as long as 12 weeks.

The rash starts with a single large patch called a herald patch. After several days, more skin rashes will appear on the chest, back, arms, and legs.

The skin rashes:

  • Are often pink or pale red

  • Are oval in shape

  • May be scaly

  • May follow lines in the skin or appear in a "Christmas tree" pattern

  • May itch

SIGNS AND TESTS

Your health care provider can usually diagnose pityriasis rosea by the way the rash looks.

Rarely, the following tests are needed:

  • A blood test to be sure it is not a form of syphilis, which can cause a similar rash

  • A skin biopsy to confirm the diagnosis

TREATMENT

If symptoms are mild, you may not need treatment.

Gentle bathing, mild lubricants or creams, or mild hydrocortisone creams may be used to soothe irritation.

Antihistamines taken by mouth may be used to reduce itching. You can buy antihistamines at the store without a prescription.

Moderate sun exposure or ultraviolet (UV) light treatment may help make the rash go away more quickly. However, you must be careful to avoid sunburn.

PROGNOSIS

Pityriasis rosea usually goes away within 6 - 12 weeks. It doesn't usually come back.
