“骨化性纤维瘤”是成纤维细胞组织的良性肿瘤,含有大量牙骨质样钙化组织,通常发生在第三个和第四个十年之间。骨化性纤维瘤是罕见的非牙源性纤维瘤,由中胚层胚层引起的牙周膜纤维骨性肿瘤3。我们报告了一个12岁的男孩,在左眼角度附近的左颞区出现肿胀。这些非肿瘤,局部破坏性肿瘤表现为累及下颌骨的骨性病变,上颌骨,zygoma,鼻旁窦,轨道,很少有乳突区域。术前CT和MRI均未明确诊断,and,因此,所有纤维骨病变均被视为鉴别诊断.手术完全切除了病灶,组织学证实它是胶结性纤维瘤。根据世界卫生组织的分类,这是一种胶结纤维瘤的变种,代表牙骨质瘤的一个亚组,也就是说,含有牙骨质的纤维骨病变。组织学上,这些是具有类似骨和牙骨质的钙化结构的纤维组织。同时进行颅骨成形术,成功的临床结果。
\"Cementifying fibroma\" is a benign tumor of the fibroblastic tissue containing masses of cementum-like calcified tissue, usually occurring between the third and fourth decades. Cementifying-ossifying fibromas are rare non-odontogenic, fibro-osseous tumors of the periodontal ligament that arise from the mesodermal germ layer3. We report a 12-year-old male child, who presented with a swelling in the left temporal region near the angle of the left eye. These non-neoplastic, locally destructive tumors present as an osseous lesion involving the mandible, maxilla, zygoma, paranasal sinuses, orbit, and rarely the petromastoid regions. The preoperative diagnosis was not clear even with CT and MRI, and, hence, all fibro-osseous lesions were considered as differential diagnosis. The lesion was surgically resected completely, and the histology confirmed it as a cementifying fibroma. According to the WHO classification, this is a variant of cementifying fibromas, which represent a subgroup of cementomas, that is, fibro-osseous lesions containing cementum. Histologically, these are fibrous tissues with calcified structures resembling bone and cementum. Cranioplasty was done simultaneously, with successful clinical results.
