Overview

Granuloma annulare (gran-u-LOW-muh an-u-LAR-e) is a skin condition that most commonly consists of raised, reddish or skin-colored bumps (lesions) that form ring patterns — usually on your hands and feet.

No one knows exactly what causes granuloma annulare. But it may be triggered by minor skin injuries and certain medications. Some types of granuloma annulare affect adults, and others typically affect children.

In most cases, granuloma annulare isn't itchy or painful, so no treatment is necessary. The lesions usually disappear on their own within two years. If you're bothered by how your skin looks, your doctor can prescribe medications that will speed the disappearance of the lesions.
