Focal cemento osseous dysplasia (FCOD) is a subgroup of benign fibro osseous lesions, which occur in a single site of tooth-bearing areas of jaws. It is usually asymptomatic and noticed accidentally through routine radiological exams. There is often no need for treatment of such lesions. This case was a 28-year-old male patient with a mixed radiolucent-radiopaque lesion in posterior part of his mandible. Based on radiographic examination, cemento ossifying fibroma (COF) was the first differential diagnosis. After the surgical removal of the lesion, histopathologic evaluation was made and the case was diagnosed as FCOD. Fortunately, after a few months of operation, there was no complication and complete bone formation was occurred.
局灶性牙骨质骨发育异常（FCOD）是良性纤维-骨病变的一个亚组，发生于颌骨牙列区的单个部位。它通常无症状，通过常规影像学检查偶然发现。这类病变通常无需治疗。该病例为一名28岁男性患者，下颌后部有一个透射线与阻射线混合的病变。根据影像学检查，骨化性纤维瘤（COF）是首要鉴别诊断。病变手术切除后进行了组织病理学评估，该病例被诊断为FCOD。幸运的是，术后几个月没有出现并发症，且有完全的骨形成。
