DISH and ankylosing spondylitis. Case report and review of the literature.

Ankylosing spondylitis (A.Sp.) and diffuse idiopatic skeletal hyperostosis (DISH), represent the most common inflammatory and degenerative enthesopathies, respectively. Despite their rather frequent occurrence in the rheumatic disease care setting, few case reports of their simultaneous presence in the same patient have appeared in the literature. We describe here a further observation and review the rheumatologic literature.
