Microangiopathy in Cases of Granuloma annulare

Abstract
10 of 16 (62.5%) patients with granuloma annulare presented microangiopathic changes in the skin. The incidence in control groups was 100% in diabetic patients, 40% in old-age patients not known as diabetics and 0 in young victims of road accidents. The frequency of the vascular findings does not seem to be shared equally by the two types of granuloma annulare, the generalized and the localized type. In the first, as in the diabetic group, microangiopathy was observed in all patients examined. Whereas, in the second it was detected in only 2 of the 8 patients. It is concluded, therefore, that from the point of view of their relation to a diabetic state, the two forms of the disorder differ from each other.
