Generalized Granuloma Annulare

Generalized granuloma annulare (GA) is an idiopathic inflammatory cutaneous disorder characterized by pinkred, arciform and annular, nonscaly, beaded papules and plaques. Granuloma annulare can be localized or generalized with perforating, patch, and palmoplantar variants. Although the pathogenesis is poorly understood, some studies have demonstrated a correlation between GA and type 1 diabetes mellitus.[68,69,70,71] Generalized GA appears to be most strongly associated with diabetes, and approximately 10% to 15% of cases occur in this population.[70,72] Because GA has been reported to precede the diagnosis of diabetes, patients with generalized or recurrent localized GA should be screened for persistent hyperglycemia with a hemoglobin A1c test.[71,73] Although some GA is selfresolving, treatment options for persevering GA include topical and intralesional steroids, isotretinoin, dapsone, tacrolimus, antimalarials, biologic medications, and psoralen plus UVA therapy.[74]
