Signs and symptoms of Behcet’s Syndrome may vary from person to person and also depending on which parts of the body are affected. Organs that are commonly affected by Behcet’s Syndrome include the following:

• Mouth
  Presence of painful mouth ulcers is the most common sign of Behcet’s Syndrome. The mouth ulcers can occur on the inner surface of the lips, gums, cheeks or tongue. They usually heal within 7 to 10 days but often recur.

• Skin
  Skin rashes are also common in Behcet’s Syndrome. Some patients develop acne-like rashes on their body, while others may develop red, raised and tender nodules on their shins. Skin rashes may clear up on their own within 10 to 14 days, but they usually recur.

• Genitals
  Patients with Behcet’s Syndrome may develop painful ulcers on their genitals. These ulcers most commonly occur on the penis or the vulva, as round, red and ulcerated lesions. They are not a form of sexually transmitted disease.

• Eyes
  Behcet’s Syndrome may cause inflammation of the eyes, known as uveitis, which presents with redness, pain and blurred vision. If not treated promptly, it can lead to blindness.

• Joints
  Behcet’s Syndrome can cause arthritis. The affected joints become swollen, red and painful due to inflammation. Joints that are commonly affected are the knees, ankles, elbows and wrists.

• Blood vessels
  Inflammation of the veins and arteries may occur, resulting in redness, pain and swelling in the arms or legs. Occasionally blood clots can occur in the vessels (thrombosis).

• Digestive system
  A variety of signs and symptoms may affect the digestive system, including abdominal pain, diarrhea or bleeding from the intestines.

• Brain
  Inflammation in the brain and nervous system may occur, causing headaches, fever, disorientation, poor balance and stroke.
