Behcet's (beh-CHETS) disease, also called Behcet's syndrome, is a rare disorder that causes inflammation in blood vessels throughout your body. The inflammation of Behcet's disease leads to numerous symptoms that may initially seem unrelated. The signs and symptoms of Behcet's disease — which may include mouth sores, eye inflammation, skin rashes and lesions, and genital sores — vary from person to person and may come and go on their own.
The exact cause of Behcet's is unknown, but it may be an autoimmune disorder, which means the body's immune system mistakenly attacks some of its own healthy cells. Both genetic and environmental factors may be responsible for Behcet's disease.
Treatment aims to reduce the signs and symptoms of Behcet's disease and to prevent serious complications, such as blindness.
