Chondromyxoid fibroma: report of three cases with predominant cortical involvement.

The clinicoradiologic and pathologic aspects of three cases of chondromyxoid fibroma of small size and predominant cortical location are reported. Because of these unusual features, the possibility of chondromyxoid fibroma was not considered on the basis of the radiographic pattern. The diagnosis was made after pathologic examination of the tissue, obtained in two cases via needle biopsy, which led to the appropriate treatment, en bloc excision.
