背景:颌骨骨肉瘤非常罕见,仅占所有骨肉瘤的6%至7%,占所有头颈部恶性肿瘤的1%。临床病理特征以及放射学特征没有特异性,这代表了一个诊断困境。的确,这种病变常被误认为是上颌骨的良性病变。
方法:我们报告了一个45岁的颌骨骨肉瘤病例,该病例在我们的服务中咨询了一个简单的无痛性口腔肿胀,该肿胀从五个月开始发展。切除病变,组织病理学报告证实诊断为颌骨骨肉瘤。
结论:骨肉瘤是一种很少进展的口腔肿瘤,可以表现为牙齿起源的良性过程。在我们的实践中,我们经常遇到用常规药物治疗的类似病例,而整个恶性过程正在进行中,可能危及生命。我们提出的案例完美地说明了这一点,由于临床上的大量投资,恶性过程在开始时就停止了。
结论:介绍这种情况的目的是引起医生的注意,即使是良性外观的任何病变都可以掩盖恶性过程。考虑这一点,并将其整合到其诊断方法中,并应通过比较临床,放射学和组织学数据。
BACKGROUND: Osteosarcomas of the
jaws are very rare accounting for only 6 to 7% of all osteosarcomas and 1% of all head and neck malignancies. The clinicopathological characteristics as well as the radiological characteristics are not specific, which represents a diagnostic dilemma. Indeed, this lesion is often mistaken for benign lesions of the maxillary.
METHODS: We report a
case of osteosarcoma of the
jaws in a 45 year man who consulted in our service for a simple painless oral swelling evolving since a five months. The lesion was excised and histopathological report confirmed the diagnosis of osteosarcoma of the jaw.
CONCLUSIONS: Osteosarcomas are a rarely progressive tumor in the oral cavity that can show up as a
case of a benign process of dental origin. During our practice, we often meet similar cases which are treated by usual medication, while a whole malignant process is in the progress and can be life-threatening. The
case we present illustrates this perfectly, and owing to a deep clinical investment, the malignant process was stopped at its start.
CONCLUSIONS: The objective of presenting this
case is to draw the attention of the doctors that any lesions even of benign appearance can hide a malignant process. Consider this point and integrate it into its diagnostic approach should be undertaken and should lead to a deepening of the clinical examination by comparing the clinical, radiological and histological data.
