【摘要】 目的提高对原发性颌骨骨内癌的认识。方法搜集临床、手术、病理证实的原发性颌骨骨内癌6例,回顾性分析其CT、临床和病理表现。结果5例发生于下颌骨,1例位于上颌骨。3例CT表现为筛孔状骨质破坏,周围形成软组织肿块。3例表现为大块溶骨性骨质破坏,在一侧形成巨大软组织肿块。2例为鳞癌,4例为腺癌,包括1例乳头状腺癌,1例黏液性乳头状腺癌;2例腺样囊腺癌。结论原发性颌骨骨内癌好发于下颌骨,CT表现为骨恶性肿瘤征象,在颌骨恶性肿瘤中应作为鉴别诊断考虑。更多还原

【Abstract】 Objective To improve the recognization of primary intraosseous carcinoma of the jaws. Method Six cases of primary intraosseous carcinoma of the jaw proved by operation, clinic and pathology were collected, and the CT imaging and clinic-pathologic finding were analyzed retrospectively. Result Five lesionslocated in the mandible, and the other one located in the maxilla. CT showed sieve-like osteolytic bone around solid masses in 3 cases and unilocular osteolytic lesion with one side solid mass in the other 3 cases. Two lesions were squamous cell carcinoma, and the other 4 lesions were adenocarcinoma, including one papillary adenocarcinoma, one mucous papillary adenocarcinoma, and two cylindroma. Conclusion Primary intraosseous carcinoma of the jaws often located in the mandible. The CT feature of primary intraosseous carcinoma of jaws was malignant sign of bone tumor. It should be included in differential diagnosis of malignancy of jaws. The strict diagnosis criteria must be applied.更多还原
