Granuloma annulare

Granuloma annulare is a skin condition that often looks like a ring of bumps. It sometimes clears up without treatment, but it can take a long time and it may come back. See a GP if you have bumps or lumps on your skin that do not go way in a few weeks.

Check if you have granuloma annulare

Granuloma annulare mainly affects children, teenagers and young adults, but older adults can get it too.

The most common symptom is small circular patches of pink, purple or skin-coloured bumps on the skin.

The patches can appear on 1 or more places on your body. They tend to affect bony areas such as the back of the hands, fingers, elbows and feet.

The patches are usually raised and grow slowly to around 2.5 to 5cm. They may eventually become flatter before gradually fading.

Granuloma annulare may be harder to see on black and brown skin.

In older adults, granuloma annulare is often made up of lots of small pink or skin-coloured bumps that cover large areas of the arms, legs or trunk (chest, tummy and back).
