Symptoms

The signs and symptoms of granuloma annulare can vary, depending on the type:

• Localized. This is the most common type of granuloma annulare. The bump (lesion) borders are circular or semicircular, with a diameter up to 2 inches (5 centimeters). The lesions occur most commonly on the hands, feet, wrists and ankles of young adults.
• Generalized. This type is uncommon and usually affects adults. It causes bumps that form a rash on most of the body, including the trunk, arms and legs. The rash might cause discomfort or itchiness.
• Under the skin. A type that usually affects young children is called subcutaneous granuloma annulare. It produces small, firm lumps under the skin, instead of a rash. The lumps form on the hands, shins and scalp.

When to see a doctor

Call your doctor if you develop a rash or bumps (lesions) in ring pattern that don't go away within a few weeks.
