title: [Common aspects between psoriatic spondylitis and ankylosing spondylitis].
abstract: In this article we review the common aspects between ankylosing spondylitis and psoriatic arthritis. These aspects are discussed at 3 fundamental levels: concept and diagnostic focus, clinical expression and impact the main domains of disease and therapeutic approach. It is concluded that there are enough arguments to consider both entities within the same concept of axial spondyloarthritis.
