title: HLA-DR and DQ antigens in lichen planus.
abstract: A study on HLA-DR and DQ typing in 40 patients with lichen planus (26 males and 14 females) and in 92 normal blood donors of both sexes was performed. Twenty-seven patients had cutaneous lesions, 11 cutaneous and mucosal involvement and 2 patients had oral erosive lesions. Serological typing revealed a highly significant increase of HLA-DR 1 antigen in the patient group. No difference has been observed on the prevalence of DR1 antigen among the different clinical status of the disease.
