ABSTRACT

The authors report a new case of mesenchymal chondrosarcoma (MCS), occurring in the upper jaw bone of a 19 year-old woman. Radiographic picture in the bone shows an aggressive osteolytic tumor suspect of malignancy. An incisional biopsy was practiced and the histologic examination has confirmed the diagnosis of MCS. Treatment have consisted of a large resection of maxilla with additional irradiation therapy. The postoperative course was marked by recurrence of the lesion one year later.
