What is 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
