A clinical study of Addison's disease.

Fifty-four patients affected by primary adrenocortical insufficiency have been retrospectively studied. Eighteen were affected by a tuberculous Addison's disease, 24 by an idiopathic Addison's disease and 12 by an unclassifiable form. Modality of arise, clinical presentation and association with other diseases are reviewed. The most useful laboratory and instrumental tests for the diagnosis are discussed and a diagnostic flow-chart is proposed.
