Vasculitis in Behçet syndrome can involve any kind and size of vessels, and this explains why the disease has the ability of multisystemic involvement. The commonest clinical presentation of Behçet syndrome is recurrent and painful mucocutaneous ulcerations known as aphthosis. The other clinical manifestations vary among patients and populations. The disease tends to be more severe in men. Ocular, vascular, and central nervous system involvements are the major causes of morbidity and mortality.
