Behçet's syndrome, or Behçet's disease (pronounced betchets) is a rare autoimmune condition that can involve mouth ulcers, genital ulcers, skin problems and eye inflammation. It's not an infection and can't be passed from one person to another.
It can also involve other areas of the body, such as the gastrointestinal tract, as well as the pulmonary, musculoskeletal, cardiovascular and neurological systems.
Because of the many different parts of the body that can be affected with Behçet's, many different medications can be used to control symptoms.
For more information, see Behçet's syndrome.
