What is this rash?
Granuloma annulare is a harmless rash that forms rings on the surface of the skin. Granuloma annulare usually does not itch, and may otherwise go unnoticed.

Is it associated with anything?
Granuloma annulare is rarely associated with diabetes. Granuloma annulare is most common in children and young adults; the reason is unknown.

How do I treat it?
Treatment of granuloma annulare is difficult and, except for the cosmetic aspect, is usually unnecessary. Sometimes, granuloma annulare responds to topical cortisone preparations. Cortisone injections can also be used to treat granuloma annulare. These are more effective than cortisone creams. The natural course of granuloma annulare, in most patients, is to eventually disappear on its own after several years.
