Abstract：
Benign osseous tumors of mesodermal origin that are included within the group of fibro-osseous lesions include cemento-ossifying fibromas (COFs). The fibrocellular component of these diseases originates from the periodontal ligament, which deposits bone and cementum encased in fibrous tissue. It typically appears in the mandible and presents as a solitary, nonaggressive, slowly developing, asymptomatic, expansile lesion, rarely occurring in the maxilla. The only intervention that proved to be successful in producing excellent outcomes and that may be regarded as a final therapeutic option is the complete surgical removal of COFs. Presenting herein is a case report describing a painless and expansile mass in the left mandibular region, histopathologically diagnosed as COF.
摘要：
包括在纤维骨病变组中的中胚层起源的良性骨性肿瘤包括牙骨质骨化性纤维瘤(COF)。这些疾病的纤维细胞成分起源于牙周膜，将骨骼和牙骨质沉积在纤维组织中。它通常出现在下颌骨中，表现为孤立的，非侵略性,缓慢发展，无症状，扩张性损伤,很少发生在上颌骨。唯一被证明能成功产生优异结果并可被视为最终治疗选择的干预措施是完全手术切除COF。本文提供的病例报告描述了左下颌区域的无痛且可膨胀的肿块，组织病理学诊断为COF。
