title: Alopecia areata: a clinical study.
abstract: 100 cases of alopecia areata are examined and the possible relationship with the presumed etiological factors (atopy, autoimmunity and psychosomatics) are looked for. When atopy or autoantibodies are present alopecia areata always runs a serve course. It is, however, impossible to establish a definite etiological relation between atopy or autoimmunity and alopecia areata.
