Chordoma is a rare cancer that universally over expresses brachyury and occurs in the base of the skull and spine.
(1) Primary nasopharyngeal ESMC can often be misdiagnosed with squamous cell carcinoma nasopharynx, melanomas, lymphomas, soft tissue sarcomas, Ewing sarcoma, skeletal chondrosarcomas, chordomas, parachordomas, myoepithelial carcinoma, myxopapillary ependymomas, chordoid meningiomas, and myxoid liposarcoma.
Sarcomas that showed positive immunoreactivity for OCN in our study were 11 cases of chondrosarcoma, 3 cases of Ewing's sarcoma, chordoma, and plasmacytoma.
In the first described case the radiological features were highly suggestive of a chordoma, dictating the choice of immediate resection, and pathological examination established the diagnosis of a thyroid carcinoma.

The tumor pathology was as follows: schwannoma ( n = 24), chordoma ( n = 16), meningioma ( n = 14), esthesioneuroblastoma ( n = 13), carcinoma ( n = 6), neuroendocrine carcinoma ( n = 5), adenocarcinoma ( n = 3), chondrosarcoma ( n = 2), angiofibroma ( n = 1), and rhabdomyosarcoma ( n = 1).
Skull base lesions, such as chordoma, chondrosarcoma, multiple myeloma and bony metastases, may grow exophytically in the basal cisterns to impinge on the nerve or may invade the Meckel's cave directly (2).
