Granuloma Annulare is a raised, bumpy or ring-shaped lesion, which can occur singly or in groups on the skin. It is more common in children and young adults, although it may affect people of all ages. Women are twice as likely as are men to develop Granuloma Annulare.
What Granuloma Annulare Looks Like:
Granuloma Annulare may be pearly white, skin-colored, red or purple. It is most often in an isolated area, but may appear as several “bumps” spread over the body. Beginning as a round, firm, smooth bump, the lesion becomes a circular ring with a clear center, which resembles the shape of a doughnut. While Granuloma Annulare can develop on any part of the skin, it appears most often on the tops of the hands and feet, elbows, and knees. It usually does not peel or itch and for that reason, can often go unnoticed.
Causes of Granuloma Annulare:
No one knows what causes Granuloma Anulare, but a reaction in the immune system may play a role. There may be a relationship between Granuloma Annulare and diabetes. So far, this remains unproven.
Having Granuloma Annulare does not mean that you are ill. Most people do not have symptoms, and the only sign is a spot on the skin. A few experience mild itching.
Other Diseases That Granuloma Annulare Looks Like:
Granuloma Annulare is most often confused with ringworm. It also may look like insect bites. One insect bite in particular may resemble Granuloma Annulare. This is the initial lesion of Lyme disease, which is called Erythema Migrans.
