Crohn's disease associated to chordoma: a case report

ABSTRACT

Crohn's disease is an inflammatory bowel disease characterized by remissions and exacerbations. Immunosuppressants are frequently used to induce and maintain remission in these patients. The use of the immunomodulator azathioprine has been associated to malignancies. Chordomas are rare, locally aggressive tumors arising from remnants of the notochord. A specific trigger for this tumor has not been identified and association to any medication has not been reported. The purpose of this report is to present the first case reported in the literature of Crohn's disease associated to a chordoma. The patient to be presented was on azathioprine therapy, among other medications. A review of literature revealed that Crohn's disease and chordoma have abnormalities in chromosomes 1 and 10. Inflammatory bowel disease and chordoma also have abnormalities in chromosomal regions 1p, 3p, and 7q. Despite these findings, a direct genetic relationship between these diseases is speculative.
