Clinical Information
  • A rare chronic inflammatory disorder of unknown etiology. It is characterized by the development of ulcers in the mouth and genital region and uveitis. Other signs and symptoms include arthritis, deep vein thrombosis and superficial thrombophlebitis.
  • Behcet's syndrome is a disease that involves inflammation of the blood vessels. It causes problems in many parts of the body. The most common symptoms are
    • sores in the mouth
    • sores on the sex organs
    • other skin sores
    • swelling of parts of the eye
    • pain, swelling and stiffness of the joints
    more serious problems can include meningitis, blood clots, inflammation of the digestive system and blindness. Doctors aren't sure what causes behcet's. It is rare in the United States, but is common in the middle east and asia. It mainly affects people in their 20s and 30s. Diagnosing behcet's can take a long time, because symptoms may come and go, and it may take months or even years to have all of the symptoms. There is no cure. Treatment focuses on reducing pain and preventing serious problems. Most people can control symptoms with treatment. nih: national institute of arthritis and musculoskeletal and skin diseases
  • Rare chronic inflammatory disease involving the small blood vessels. It is of unknown etiology and characterized by mucocutaneous ulceration in the mouth and genital region and uveitis with hypopyon. The neuro-ocular form may cause blindness and death. Synovitis; thrombophlebitis; gastrointestinal ulcerations; retinal vasculitis; and optic atrophy may occur as well.
