title: Axial psoriatic arthritis: an intriguing clinical entity or a subset of an intriguing disease?
abstract: This article summarizes the state of the art of axial involvement in psoriatic arthritis (axial PsA). The definition and measurement of axial disease in PsA still remain problematic, and this, in turn, could affect the best approach of recognition and treatment of this intriguing subset of the psoriatic disease. Axial PsA has been studied over the last few years looking at the difference in function and radiological finding compared to ankylosing spondylitis (AS), trying to differentiate it from a coincidental AS with psoriasis. Finally, this review has described the diagnosis and treatment of axial PsA reporting the data obtained from the literature.
