Behçet’s disease (BD), a chronic vasculitis affecting any type of the blood vessels, was first described by a Turkish dermatologist Hulusi Behçet. Although it has a worldwide distribution, it is commonly seen in the Silk Road countries around the Mediterranean Sea. The country in which the disease is most commonly seen is Turkey with a prevalence of 20–602/100,000. The disease most appears between the second and fourth decades of the life. BD affects both genders equally. However, the gender distribution may differ among different regions.
