GlossaryGranuloma Annulare

chronic skin condition with ring-shaped, raised bumps

Granuloma Annulare (GA) is a chronic skin condition characterized by the formation of small, firm, raised bumps that often form ring-like patterns, typically on the hands, feet, elbows, or knees. The exact cause is unknown, but it is believed to be related to immune system activity, and while it is generally harmless and often resolves on its own, it can sometimes be associated with other conditions like diabetes or thyroid disease.
