Picture of Granuloma Annulare
Granuloma annulare is a condition that causes expanding bumps on the skin that are reddish or flesh colored. A ring often appears around the bumps. The exact cause of the condition is unknown. It most often occurs in older children or young adults. The lesions usually occur on skin covering joints like the knuckles or elbows. They may also appear on the backs of the hands and the tops of the feet. People who have the condition may experience severe itching or no symptoms. Most cases resolve on their own within a few years without treatment. In some cases, prescription cortisone cream may be applied to the lesions to help relieve symptoms.
