Prolonged small vessel vasculitis with colon mucosal inflammation as first manifestations of Behçet's disease.

Behçet's disease is a chronic, relapsing, systemic vasculitis of unknown aetiology. Patients present manifestations of gastrointestinal complications, including mouth lesions, small and large intestinal lesions, and vascular lesions in the abdomen. In some cases, the intestinal ulcers of patients with Behçet's disease are indistinguishable from those of Crohn's disease, tuberculosis, vasculitis and other diseases. In this article, we present a case of atypical Behçet's disease with a complicated medical history and multisystem damage, for the purpose of better management of this disease.
