SymptomsBy Mayo Clinic staff
Behcet's disease symptoms vary from person to person. Behcet's disease may disappear and recur on its own. The signs and symptoms that you may experience depend on which parts of your body are affected by the inflammation of Behcet's disease. Areas commonly affected by Behcet's disease include:
- Mouth. Painful mouth sores, that look similar to canker sores, are the most common sign of Behcet's disease. Sores begin as raised, round lesions in the mouth that quickly turn into painful ulcers. The sores heal usually in about one to three weeks, though they do recur.
- Skin. Skin lesions may occur in people with Behcet's disease. Skin problems can vary. Some people may develop acne-like sores on their bodies. Others may develop red, raised and tender nodules on their skin, especially on the lower legs.
- Genitals. People with Behcet's disease may develop sores on their genitals. The sores commonly occur on the scrotum or the vulva. Sores appear as red, ulcerated lesions. The genital sores are usually painful and may leave scars.
- Eyes. Behcet's disease may cause inflammation in the eye — a condition called uveitis (u-vee-I-tis). In people with Behcet's disease, uveitis causes redness, pain and blurred vision in one or both eyes and may come and go. Inflammation that occurs in the blood vessels of the retina is a serious complication of the disorder.
- Joints. Joint swelling and pain often affect the knees in people with Behcet's disease. The ankles, elbows or wrists also may be involved. Signs and symptoms may last one to three weeks and go away on their own.
- Vascular system. Inflammation in veins and large arteries may occur in Behcet's disease, causing redness, pain and swelling in the arms or legs when a blood clot results. In fact, many of the signs and symptoms of Behcet's are believed to be caused by inflammation of the blood vessels (vasculitis). Inflammation in the large arteries can lead to complications, such as aneurysms and narrowing or blockage of the vessel.
- Digestive system. Behcet's disease may cause a variety of signs and symptoms that affect the digestive system, including abdominal pain, diarrhea or bleeding.
- Brain. Behcet's disease may cause inflammation in the brain and nervous system that leads to headache, fever, disorientation, poor balance or stroke.
