Abstract		Background. Maxillofacial sarcomas are rare tumours and osteosarcoma of the jaws is an exceptionally rare entity. Unlike osteosarcoma of the long bones, maxillofacial osteosarcomas are reported to occur in the third or fourth decades. Case report. We report an 18-year-old female patient with the histopathologic diagnosis of osteoblastic osteosarcorna of the maxillary bone on the basis of computerized tomographic findings. Following the initial surgery and the adjuvant chemo-radiotherapy, a massive local recurrence developed in the facial region of the patient within two years. Conclusions. The radiographic evaluation of the osteosarcoma of the maxilla is important in the diagnosis and obtnining a cornplete surgical therapy. CT examination of this region after plain radiography plays a major role at the diagnosis.
Summary		Izhodišča. Maksilofacialni sarkomi so redki tumorji, še redkejši pa so osteosarkomi čeljusti. V nasprotju z osteosarkomi dolgih kosti se maksilofacialni pojavljajo predvsem v 3. in 4. desetletju življenja. Prikaz primera. Opisujemo 18-letno bolnico, ki smo ji histološko potrdili osteoblastični osteosarkom maksile po predhodni preiskavi z računalniško tomografijo (CT). Čeprav smo bolnico radikalno operirali in nato adjuvantno zdravili s kemoradioterapijo, smo čez dve leti na obrazu ugotovili obsežno lokalno ponovitev bolezni. Zaključki. Radiografska ocena osteosarkoma maksile je pomembna preiskava - zlasti CT - saj omogoča ob diagnozi načrtovanje radikalne operacije.
