[Massive gastrointestinal bleeding due to aneurysmal rupture of ileo-colic artery in a patient with Behcet's disease].

Behcet's disease has been recognized as a systemic vasculitis characterized by the involvement of multiple organs such as orogenital ulcers, eye lesions including uveitis and optic neuritis, and skin lesions including folliculitis and erythema nodosum. Vascular involvement occurs occasionally and is classified into thrombosis and aneurysm. However, massive gastrointestinal bleeding from arterial aneurysm is a rare manifestation of intestinal Behcet's disease.
