Case report: a pediatric case of cementoblastoma with histologic and radiographic features of an osteoblastoma and osteosarcoma.
One case of an expansile mass involving the roots of a mandibular left first molar in a nine year old male is presented. The lesion has features of a cementoblastoma (CB), osteoblastoma (OB), and osteosarcoma (OS) both radiographically and histologically. Radiographically, a "sunburst" appearance is present. Histologically, the lesional tissue is intimately involved with the root, not the periosteum. The clinical, radiographic, and histopathologic characteristics of CB, OB, and OS are discussed as well as the difficulties associated with distinguishing between these lesions in the gnathic region.
