What it is
It usually goes away on its own within a few months to 2 years, although it can come back.
Treatment is not always needed. Steroid creams or other treatments may help if the rash is widespread or bothersome.
Common signs
- A ring of small, smooth, raised bumps
- Skin-coloured, pink or purple patches
- Mild itching, sometimes
How it is usually diagnosed
- Examination of the skin
- A skin biopsy, sometimes
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Dermatology letters
- Biopsy results
- Photos of the rash over time
Questions to ask your doctor
- Is it definitely granuloma annulare?
- Does it need treatment?
- Is it linked to any other condition?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A rash that spreads quickly with fever or feeling unwell: get it checked the same day
