PowerPoint Presentation: Behçet's disease (BD) was named in 1937 after the Turkish dermatologist Hulusi Behçet , who first described the triple-symptom complex of recurrent oral aphthous ulcers genital ulcers uveitis recurrent oral aphthous ulcers : recurrent oral aphthous ulcers PowerPoint Presentation: As a systemic disease, it can also involve visceral organs such as the gastrointestinal tract pulmonary musculoskeletal and neurological systems This syndrome can be fatal due to ruptured vascular aneurysms or severe neurological complications. Skin and mucosa : Skin and mucosa aphthous ulcers inflammatory bowel disease erythema nodosum pyoderma gangrenosum aphthous ulcers: aphthous ulcers inflammatory bowel disease : inflammatory bowel disease erythema nodosum: erythema nodosum pyoderma gangrenosum : pyoderma gangrenosum Ocular system : Ocular system posterior uveitis , anterior uveitis , or retinal vasculitis Bowels : Bowels GI manifestations include abdominal pain, nausea, and diarrhea with or without blood, and they often involve the ileocecal valve. Many patients with BD often complain about abdominal tenderness, bloating, and generic abdominal discomfort that closely mimics irritable bowel syndrome. Lungs : Lungs Lung involvement is typically in the form of hemoptysis , pleuritis , cough, or fever, and in severe cases can be life threatening if the outlet pulmonary artery develops an aneurysm which ruptures causing severe vascular collapse and death from bleeding in the lungs Musculoskeletal system : Musculoskeletal system Arthralgia is seen in up to half of patients, and is usually a non-erosive poly or oligoarthritis primarily of the large joints of the lower extremities Neurological system : Neurological system Neurological involvements range from aseptic meningitis to vascular thrombosis such as dural sinus thrombosis and organic brain syndrome manifesting with confusion, seizures, and memory loss They often appear late in the progression of the disease but are associated with a poor prognosis.
