[Dedifferentiated (sarcomatoid) chordoma in the base of the skull. Report of a case].
We report a case of "dedifferentiated" chordoma occurring in a 31-year-old man and involving the base of the skull. Morphologically, the tumor was characterized by a bifasic pattern (classical chordoma associates to sarcoma-like areas), and by coexpression of epithelial and stromal markers. Because of these traits, we believe this case shows features superimposable to those seen in sarcomatoid carcinoma.
