Sequential appearance of ankylosing spondylitis, retroperitoneal fibrosis and achalasia: Coincidental association or evidence of autoimmunity?
The association of idiopathic achalasia with ankylosing
spondylitis and retroperitoneal fibrosis, to our knowledge
not previously reported, is described in a 54 year old woman.
We suggest that the consecutive occurrence of ankylosing
spondylitis and retroperitoneal fibrosis, two well-known
autoimmune disorders, before the presence of achalasia,
reinforces the theory of autoimmunity in etiopathogenesis
Key words: Achalasia, Ankylosing spondylitis, Retroperitoneal fibrosis, Autoimmunity
