What is granuloma annulary?
Granuloma annulare (GA) is a common condition of unknown cause. It appears most often over knuckles and other joints or in places that are subject to frequent, mild injury such as the back of the hands or top of the feet. It is seen most often in older children and young adults. The “rash” of GA is symmetrical (appears on both sides of the body more or less evenly) and formed by skin colored bumps. The bumps often expand or join to form rings. The center of each ring may be a little depressed, pale or light brown. GA usually has no symptoms, but it may be tender. It may come and go, only to return again. Most cases clear up after a few years with or without treatment. Sometimes the diagnosis is not obvious, and other conditions may be considered. In such cases, a small biopsy will help to confirm the diagnosis. In most cases no treatment is required. If treatment is desired, it may be helpful to apply a prescription cortisone cream to the skin. Cortisone can be injected into the lesion
