Your health care provider may diagnose granuloma annulare by looking at the affected skin and taking a small skin sample (biopsy) to examine under a microscope.


Granuloma annulare can clear on its own over time. Treatment might help clear the skin faster than if left untreated, but the condition often returns. The bumps that return after treatment tend to appear at the same spots, and 80% of those usually clear within two years.

Untreated, the condition might last a few weeks or decades.

Treatment options include:

  • Corticosteroid creams or ointments. Prescription-strength products may help clear the skin faster. Your health care provider may direct you to cover the cream with bandages or an adhesive patch, to help the medicine work better.
  • Corticosteroid injections. If the skin isn't clearing up with a medicated cream or ointment, your health care provider may suggest a corticosteroid injection. Repeat injections may be needed every 6 to 8 weeks until the condition clears up.
  • Freezing. Applying liquid nitrogen to the affected area may help remove the bumps.
  • Light therapy. Exposing the affected skin to certain types of light, including lasers, is sometimes helpful.
  • Oral medicines. When the condition is widespread, your health care provider might prescribe medicine taken by mouth, such as antibiotics or antimalarials.

Coping and support

These coping methods might help ease the distress of living with granuloma annulare long term:

  • Routinely reach out to friends and family members.
  • Join a local or reputable internet-based support group.

Preparing for your appointment

You're likely to start by seeing your primary care provider, who may then refer you to a specialist in skin conditions (dermatologist).

What you can do

Before your appointment, you might want to list answers to the following questions:

  • Have you recently traveled to a new area or spent much time outdoors?
  • Do you have pets, or have you recently had contact with new animals?
  • Are any family members or friends having similar symptoms?
  • What medicines or supplements do you take regularly?

What to expect from your doctor

Your health care provider is likely to ask you a number of questions, such as those listed below. Being ready to answer them may reserve time to go over any points you want to spend more time on.

  • When did your skin condition first appear?
  • Does your rash cause any discomfort? Does it itch?
  • Have your symptoms become worse or stayed the same over time?
  • Have you been treating your skin condition with any medicines or creams?
  • Does anything seem to improve — or worsen — your symptoms?
  • Do you have any other health conditions, such as diabetes or thyroid problems?
