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.
原发性颌骨内原发性癌极为罕见。我们报告了一例这种不常见肿瘤的新病例，并讨论了其组织病理学和临床方面。该患者为 76 岁男性，因左下颌牙龈疼痛和改变就诊。全景片和 CT 显示下颌大透亮区。行节段性下颌骨切除术，组织病理学检查证实肿瘤为骨内鳞状细胞癌。尽管进行了适当的手术治疗，外科医生仍应认识到这种肿瘤的侵袭性。
