What Is Behcet's Disease

What is Behcet's disease?

The first case of Behcet's disease was reported by Turkish dermatologist Bechet in 1937, which is also the origin of the name of Behcet's disease.

Behcet's disease is also called "Behcet's syndrome" or "mouth-eye-genital syndrome". From the name behind, we can see the manifestations of Behcet's disease: repeated ulceration of the mouth and reproductive organs, blurred vision of the eyes, decreased vision, and skin lesions similar to whelk-like and red induration-like lesions. When the condition is serious, lesions will appear in joints, digestive tract and nervous system, and varicose veins like earthworms will appear in the skin of lower limbs.

It is also called "Silk Road Disease" because of its high incidence in South Korea, Japan, China, Turkey and Iran.

The specific etiology of Behcet's disease is still unclear, and it is likely to occur in young and middle-aged people. There are more male patients than female patients, and the male patients' condition is relatively serious.

At present, Behcet's disease cannot be cured completely and it is easy to relapse. However, regular treatment as early as possible after the diagnosis is conducive to controlling the existing symptoms, preventing and treating important organ damage and slowing the disease progression.

Is Behcet's disease more common?

Rare. The prevalence in China is (13.5–20)/100 000.


What Is The Cause Of Behcet's Disease

What is the cause of Behcet's disease?

The pathogenesis of Behcet's disease is currently unclear and may be related to genetic, environmental, infectious, immune and other factors, as follows:

  • Heredity: Studies have found that some patients with Behcet's disease have a clear family genetic history.

  • Environment: The incidence and region of Behcet's disease have been existed before, and it mostly occurred in the Mediterranean Sea, Middle East, China and Japan.

  • Infection: Studies have found that Behcet's disease may be related to viral and bacterial infections and may also be related to tuberculosis.

  • Immunity: The body of patients with Behcet's disease produces antibodies against the oral mucosa and blood vessel wall, which means that the oral mucosa and blood vessel wall are labeled as "enemies", making the body's immune system treat them as enemies and attack them, causing lesions in the oral mucosa and blood vessel wall.

What kind of people is Behcet's disease common in?

Behcet's disease mainly occurs in young and middle-aged people aged 16–40 years old. There are more male patients than female patients, and male patients are more prone to ocular, nervous system and vascular lesions, and the condition is generally more serious.

What is the specific oral lesion of Behcet's disease?

Patients with Behcet's disease generally suffer from oral ulceration, which is mainly located in the tongue, lips, gums, gills and other areas. The patients have round or oval ulcerated surfaces, which can be one or more in number, with a clear boundary. If the ulcerated surface is deeper, scars will be left after healing, and the patients will feel great pain. The ones with severe pain will affect eating.
