Granuloma Annulare

"Granuloma" means a small mass of tissue that forms because of inflammation (swelling). "Annulare" means shaped like a ring.

Granuloma annulare is a harmless skin reaction that causes small, firm, raised bumps on the skin. The bumps form a ring with normal or slightly sunken skin at the center of the ring.

Granuloma annulare is more common in women
You may have a single ring or several rings
Granuloma annulare usually heals without treatment

Doctors don't know what causes granuloma annulare. It may be a reaction from your immune system.

Symptoms include small, firm, raised bumps that form on your feet, legs, hands, or finger in a ring shape. The bumps can be bluish, yellowish, or skin-colored. They may be tender.

Doctors can tell you have granuloma annulare by looking at your skin. To know for sure, doctors may do a biopsy (taking a small piece of skin to look at under a microscope).

Granuloma annulare usually heals without any treatment. If it bothers you, doctors treat it with:

Corticosteroid creams or shots
Skin cream to treat an immune reaction
Light therapy with medicines to make your skin more sensitive to light
Other medicines or laser therapy
