HLA-A and -B antigen frequencies were studied in 78 patients, 35 with localized granuloma annulare and 43 with generalized granuloma annulare (GA). Twenty-eight patients in each group were also typed for HLA-DR antigens. A group of 200 healthy age-matched subjects served as controls. HLA-A31 and B35 were increased significantly in patients with generalized GA, but not in the localized form. HLA-DR antigen distribution showed no significant variation.
