Osteochondroma in a Patient with Juvenile Ankylosing Spondylitis Associated with Idiopathic Thrombocytopenic Purpura and a Thalassemia

Abstract

An unusual combination of osteochondroma, ankylosing spondylitis, thalassemia a, and thrombocytopenia was found in a young man who had once been an amphetamine addict. The association of these settings might have been coincidental but it cannot be excluded that the preexisting inflammatory processes or tissue destruction in the latter 3 diseases might have rendered the patient prone to the development of osteochondroma.
