Definition
By Mayo Clinic staffGranuloma annulare (gran-u-LOW-muh an-u-LAR-ee) is a chronic skin condition consisting of raised, reddish or skin-colored bumps (lesions) that form ring patterns, usually on your hands, feet, elbows and knees.
Although the lesions may be unsightly, granuloma annulare usually causes no other symptoms and has no long-term impact on your health. Still, granuloma annulare can be hard to cope with if your lesions affect your appearance.
In most cases the lesions disappear on their own within two years. If you choose treatment of granuloma annulare for cosmetic reasons, your doctor may prescribe corticosteroids to improve the appearance of the lesions and speed their disappearance.
