We report a case of a woman presenting a giant cementoossifying fibroma depending of the mandibular gingivae. The evolution of the process was 20 years. Cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. This lesion appears within the bone although in some occasions it involves the gingivae soft tissues, as the case we present. It is a slow-growing and well-defined tumorous lesion, because of this, it is considered as a benign lesion. The histologic findings alone may be similar to other pathologies such as osteoblastoma, low-grade osteosarcoma and particularly to fibrous dysplasia. An accurate diagnosis requires careful clinical, radiological and histological correlation in order to make an optimal treatment and an excellent outcome.
我们报告一例女性患者，其下颌牙龈处出现巨大的牙骨质骨化纤维瘤。病程长达20年。牙骨质骨化纤维瘤是一种相对罕见的肿瘤，归类于纤维骨性病变。这种病变出现在骨内，不过在某些情况下它会累及牙龈软组织，就如我们所呈现的病例。它是一种生长缓慢且边界清晰的肿瘤性病变，因此被认为是良性病变。仅组织学表现可能与其他病理情况相似，如成骨细胞瘤、低级别骨肉瘤，尤其是骨纤维异常增殖症。准确的诊断需要仔细的临床、放射学和组织学关联，以便进行最佳治疗并获得良好预后。
