[The immunological aspects of Behçet's syndrome]

The present paper reviews the basic clinical symptoms and associated manifestations in Behçet's syndrome, emphasizing the general character of the disease due to generalized vasculitis. The nature of the disease is discussed in view of recent data referring to the immunologic aspects. It is now accepted that a viral infection plays a role in triggering the disease and that continuous changes predominate the immune system modifying the varied clinical picture of Behçet's syndrome.
