Behcet’s disease is a chronic, multisystem autoimmune disease involving inflammation of blood vessels, called vasculitis, throughout the body. It is a rare disease, most commonly found in the Eastern Mediterranean countries and in eastern Asia. It affects more young men than women in those countries, but in the US it affects more women, most often in their 20s and 30s. The central nervous system, heart, and intestinal tract may be involved. Because this disease is so rare and it’s symptoms overlap those of other diseases, it may be very difficult to diagnose. Spontaneous remission may occur, which can add to the difficulty in diagnosis.
