Behçet’s disease, also known as Behçet’s syndrome, is a rare, chronic, multisystem inflammatory disorder characterized by recurrent oral and genital ulcers, skin lesions, and inflammation in the eyes. This condition is named after the Turkish dermatologist Hulusi Behçet, who first described it in 1937.
The exact cause of Behçet’s disease remains unclear, but it is believed to involve a combination of genetic, immunologic, and environmental factors. Certain genetic variations, particularly within the HLA-B51 gene, have been associated with an increased susceptibility to Behçet’s disease. Additionally, abnormalities in the immune system, including inappropriate activation of certain immune cells and the release of pro-inflammatory cytokines, play a role in the development of this condition. Environmental factors such as infections may also trigger or exacerbate symptoms in susceptible individuals.
The hallmark symptom of Behçet’s disease is recurrent oral ulcers, which typically present as painful sores in the mouth. These ulcers may vary in size and frequency and often heal spontaneously within one to three weeks. In addition to oral ulcers, individuals with Behçet’s disease may experience genital ulcers, which are painful sores on the genitals or around the anus. Skin lesions, such as erythema nodosum or papulopustular lesions, are also common manifestations of the disease.
Ocular involvement is a serious complication of Behçet’s disease and can lead to significant visual impairment or blindness if left untreated. Uveitis, inflammation of the uvea (the middle layer of the eye), is the most common ocular manifestation and may present with symptoms such as eye pain, redness, blurred vision, and sensitivity to light. Other ocular complications include retinal vasculitis, which can cause retinal hemorrhages and vision loss, as well as optic neuritis and glaucoma.
Behçet’s disease can also affect various other organ systems, leading to a wide range of symptoms. These may include joint pain and swelling (arthritis), gastrointestinal symptoms such as abdominal pain and diarrhea, neurological manifestations such as headaches, meningitis, or strokes, and vascular involvement resulting in blood clots or aneurysms. The severity and combination of symptoms can vary widely among affected individuals, and the course of the disease may be unpredictable, with periods of flare-ups alternating with periods of remission.
Diagnosis of Behçet’s disease is based on clinical criteria, as there is no specific test to confirm the condition. The diagnosis is primarily clinical and relies on the presence of characteristic symptoms such as recurrent oral ulcers plus any two of the following: genital ulcers, eye inflammation, skin lesions, or a positive pathergy test (a hypersensitivity reaction to skin puncture). Laboratory tests, imaging studies, and other procedures may be performed to rule out other conditions and assess the extent of organ involvement.
Treatment of Behçet’s disease aims to relieve symptoms, control inflammation, and prevent complications. The approach to treatment may vary depending on the severity and manifestations of the disease in each individual. Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to alleviate pain and inflammation, while topical medications such as corticosteroids or mouthwashes containing corticosteroids can help manage oral ulcers.
For more severe or widespread disease, systemic medications may be prescribed to suppress the immune system and reduce inflammation. These may include corticosteroids, immunosuppressive drugs such as azathioprine, methotrexate, or cyclosporine, and biologic agents such as tumor necrosis factor (TNF) inhibitors. In cases of ocular involvement, corticosteroid eye drops, along with systemic immunosuppressive therapy, are often necessary to control inflammation and preserve vision.
In addition to medical treatment, lifestyle modifications such as avoiding triggers that exacerbate symptoms, maintaining good oral hygiene, and protecting the eyes from sunlight and other environmental irritants can help manage Behçet’s disease. Regular monitoring by healthcare professionals is essential to assess disease activity, monitor for potential complications, and adjust treatment as needed.
Overall, Behçet’s disease is a complex and challenging condition that requires a multidisciplinary approach to management involving rheumatologists, dermatologists, ophthalmologists, and other specialists. While there is currently no cure for Behçet’s disease, ongoing research continues to improve our understanding of the underlying mechanisms and develop more effective treatments to improve outcomes and quality of life for individuals affected by this condition.

Behçet’s disease is a systemic vasculitis, meaning it involves inflammation of blood vessels throughout the body. This inflammation can affect blood vessels of all sizes, from small veins and arteries to larger vessels like the aorta. The exact mechanism by which inflammation occurs in Behçet’s disease is not fully understood, but it is believed to involve an abnormal immune response against the body’s own tissues, leading to widespread inflammation and tissue damage.
Genetic factors play a significant role in the development of Behçet’s disease, as evidenced by the increased prevalence of the condition in certain ethnic groups, particularly those of Mediterranean, Middle Eastern, and Asian descent. Studies have identified several genetic variations associated with an increased susceptibility to Behçet’s disease, with the strongest genetic association found with the HLA-B51 gene. However, not all individuals with these genetic predispositions develop the disease, indicating that environmental factors likely play a triggering role.
Environmental factors such as infections have been proposed as potential triggers for Behçet’s disease, although the specific infectious agents involved remain unclear. Some studies have suggested a possible role for bacteria, viruses, or other microorganisms in initiating or exacerbating the inflammatory response seen in Behçet’s disease. However, no single infectious agent has been consistently implicated, and the exact relationship between infection and disease onset remains an area of ongoing research.
Behçet’s disease is characterized by recurrent episodes of inflammation and tissue damage, leading to the hallmark symptoms of the condition. Oral ulcers are the most common symptom, affecting nearly all individuals with Behçet’s disease at some point during the course of their illness. These ulcers typically present as painful sores inside the mouth, on the tongue, lips, or gums, and can recur multiple times throughout the year.
Genital ulcers are also common in Behçet’s disease, affecting both men and women. These ulcers are similar to oral ulcers but occur on the genitals or around the anus and can cause pain, discomfort, and difficulty with urination or sexual activity. Skin lesions are another characteristic feature of Behçet’s disease and can take various forms, including erythema nodosum (painful red nodules on the skin) and papulopustular lesions (pimple-like bumps filled with pus).
Ocular involvement is a serious complication of Behçet’s disease and can lead to permanent vision loss if not promptly treated. Uveitis, inflammation of the uvea (the middle layer of the eye), is the most common ocular manifestation and can cause symptoms such as eye pain, redness, blurred vision, and sensitivity to light. Other ocular complications include retinal vasculitis, which can lead to retinal hemorrhages, exudates, and vision loss, as well as optic neuritis, glaucoma, and cataracts.
In addition to oral, genital, and ocular symptoms, Behçet’s disease can also affect other organ systems, leading to a wide range of manifestations. Joint involvement, known as Behçet’s arthritis, can cause pain, swelling, and stiffness in the joints, particularly in the knees, ankles, and wrists. Gastrointestinal symptoms such as abdominal pain, diarrhea, and gastrointestinal bleeding may occur due to inflammation of the digestive tract. Neurological complications, including headaches, meningitis, strokes, and seizures, can also occur in some individuals with Behçet’s disease.
The course of Behçet’s disease can vary widely among affected individuals, with some experiencing mild symptoms that come and go over time, while others may have more severe and debilitating disease with frequent flare-ups and complications. Treatment aims to control inflammation, alleviate symptoms, and prevent complications, often requiring a combination of medications and lifestyle modifications.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to relieve pain and inflammation, while topical corticosteroids or mouthwashes containing corticosteroids can help manage oral ulcers. For more severe or widespread disease, systemic medications such as corticosteroids, immunosuppressive drugs, and biologic agents may be prescribed to suppress the immune system and reduce inflammation.
In cases of ocular involvement, corticosteroid eye drops, along with systemic immunosuppressive therapy, are often necessary to control inflammation and preserve vision. Regular monitoring by healthcare professionals is essential to assess disease activity, monitor for potential complications, and adjust treatment as needed.
Despite ongoing research efforts, there is currently no cure for Behçet’s disease, and management focuses on controlling symptoms and preventing complications. However, advances in understanding the underlying mechanisms of the disease and the development of targeted therapies offer hope for improved outcomes and quality of life for individuals living with Behçet’s disease.
