Introduction: notochord. Although histologically benign, these tumors are locally aggressiveand present significant managment challenges . There arew some studies onevaluated the location, age and gender of the patients with Chordoma in tworeferral centers in Tehran.chordoma cases but there was no study about Iranian cases.

In adults 33.3% ofchordomas involve the sacrococcygeal region, 53% occured at the base of theskull near the spheno-occipital area, and near 14% were found in the vertebralcolumn. The cranial nerves mostly affected were abducens, oculomotor andtrochlear, with some overlaps. All patients were treated with surgery and somecases referred for gamma-knife radiosurgery (GKS).In our subjects tumors affect men nearly twice as frequently asDiscussion: to females that is different from other studies, however, few studies reportedmore male to female ratio. Despite the progress in current surgical techniquesand some encouraging results with the use of targeted therapy, disease controland long-term prognosis of patients are still poor.Findings of this study showed more involvement of males compare
