Granuloma annulare is a fairly rare, chronic dermatological condition which presents as reddish bumps on the skin arranged in a circle or ring. It can initially occur at any age and is significantly more common in females (80/20 ratio).
Granuloma annulare can occur on any site of the body and is occasionally quite widespread. It only affects the skin and is considered harmless. Granuloma annulare may cause no symptoms, but affected areas are often tender when knocked. The plaques tend to slowly change shape, size and position.
