Granuloma annulare is a skin condition where small, firm bumps form ring-shaped patterns. The bumps are smooth, non-scaly, and red-brown or purple. They are not painful and usually do not itch. They often appear on the back of the hands and feet, sometimes on the forearms, elbows, or lower legs. Usually, it remains limited to a few spots.
