Primary de novo intraosseous carcinoma : report of a new case

Primary de novo intraosseous carcinoma of the jaws has been rarely reported. We present a new case of this unusual tumour and discuss its histopathological and clinical aspects. The subject was a 76-year-old man who was seen due to complaints of pain and the presence of gingival changes in the left mandible. A panoramic radiograph and computed tomography revealed a large mandibular radiolucency. A segmentary mandibulectomy was performed and histopathologic examination proved that the tumour was an intraosseous squamous cell carcinoma. Surgeons should appreciate the aggressiveness of this tumour, despite adequate surgical treatment
