Behçet’s disease (BD) is a disease which has effects on different systems. Genital ulcer, aphthous stomatitis and iritis are characterized by triple symptom complex of BD. BD is considered to be a systemic vasculitis. BD was previously accepted in spondyloarthropathy (SSpA) group, but there are many reasons for not classifying BD as one of SSpA group. Ankylosing spondylitis (AS) is a prototype of seronegative spondyloarthropathy, and mainly axial skeleton is affected. In this paper, we aimed to present a-33-year old female patient with coexistence of BD and AS. In addition, the coexistence was aimed to be discussed.
