Areas of chordoma and chondrosarcoma have been reported extensively in the same tumoral mass located in espheno-palatine region. The same association in long bones of the extremities have been reported recently, with the name of "chordoide sarcoma", "parachordoma" or "chondroid chordoma". We present a case of "chordoid sarcoma". The cells of this tumor have morphologic features of chordoma and chondrosarcoma in both the optical and ultrastructural study. However some morphological, radiological and clinical aspects, suggest that this tumor possesses characteristics that define it as a separate entity.
