Abstract
Background
An overlap syndrome of Behçet’s disease and ankylosing spondylitis is a rare autoimmune disease of connective tissue in which a patient presents with symptoms of two diseases.
Case presentation
We report a case of non-smoking 25 years old known to have ankylosing spondylitis presented by haemoptysis due to a cause not usually associated with his primary disease leading to the search for another cause.
Conclusion
The coexistence of Behçet’s disease and ankylosing spondylitis may be encountered in clinical practice, although it is rare. If there is a resistance to the conservative treatments, TN-alpha blocking agents may be an alternative therapeutic option in these diseases.
