This is a skin disease seen usually in children and young adults. It is occasionally associated with diabetes. Skin signs are characterised by red spots in the initial stages which expand outwards in a ring-like fashion. The hands, especially the fingers, and elbows are commonly affected. When granuloma annulare is widespread it may be associated with underlying diabetes mellitus. The skin lesions may precede the symptoms and signs of diabetes mellitus. Patients with widespread granuloma annulare need to be screened for diabetes mellitus.
