"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. [ABSTRACT FROM AUTHOR] |
