Behcet's disease (also known as Behcet's syndrome) is a type of vasculitis.
Vasculitis is a condition in which the blood vessels are inflamed. The inflammation of the blood vessels causes blood flow to be restricted. As a result, there is pain and tissue damage at the site of the affected organ or body part.
Behcet's disease can occur anywhere in the world and in people of any ethnic background. It is especially noted, however, in Asian countries along the "old silk route," extending from Turkey in the west overland to Japan in the east. It is far more prevalent in Turkey, China, Iran, Iraq, and Japan than in North America, Europe, or the southern hemisphere.
Behcet's disease may occur in men or women, although it may be more severe in male patients. People of any age can get Behcet's, but it generally occurs in people ages 20-50.
