The signs and symptoms of granuloma annulare can vary, depending on the variety:
- Localized. This is the most common type of granuloma annulare. The lesion borders have a circular or semicircular shape, with a diameter up to 2 inches (5 centimeters). It occurs most commonly on the hands, feet, wrists and ankles of young adults, particularly women.
- Generalized. Up to 15 percent of the people who have granuloma annulare have lesions over a large portion of their bodies — including the trunk, arms and legs. This variety is more likely to be itchy and most often affects adults.
- Subcutaneous. Occurring predominantly in young children, this type of granuloma annulare produces a firm lump under the skin instead of a rash. The lump is usually less than 1.5 inches (3.8 centimeters) in diameter.
When to see a doctor
Call your doctor if your skin develops reddish bumps (lesions) in ring patterns that don't go away within a few weeks.
