A Case of Ankylosing Spondylitis Associated with Turner's Syndrome

ABSTRACT

Turner's syndrome (TS) is a chromosomal disorder where phenotypic females have either a missing chromosome (45 XO) or a structural aberration in one of the chromosomes. Previous studies have suggested that women with TS may be at increased risk of several autoimmune diseases, such as Hashimoto thyroiditis, celiac disease, Crohn's disease, ulcerative colitis, juvenile rheumatoid arthritis, and vitiligo. Although a high risk has been documented for autoimmune diseases in TS, there is only one case reporting the relationship between TS and ankylosing spondylitis (AS) in the literature. Herein, we present an unusual case of AS associated with TS.
