“…In certain cases, the typical 'sunray' appearance may be observed at the periphery of the tumor in plain radiographs and computed tomography scans. The hallmark of cementoblastoma is the sharp border between the tubular dentin of the root and the cementum-like A B component (15). In the present case, the osteosarcoma resembling cementoblastoma mimicked 'benign' bone growth, and there was no observation of the typical 'sunray' radiographical appearance.…”

Abstract. Cementoblastoma is a form of benign odontogenic tumor, with the preferred treatment consisting of tooth extraction and follow-up examinations, while in certain cases, follow-up examinations without surgery are performed. Osteosarcoma of the jaw is a rare, malignant, mesenchymal tumor, associated with a high mortality rate and low incidence of metastasis. Cementoblastoma and osteosarcoma of the jaw are dissimilar in terms of their histological type and prognosis; however, there are a number of covert associations between them. The present study describes the case of a 20-year-old female with an unusual swelling in the left mandible that had been present for 2 years. The patient was initially clinically diagnosed with cementoblastoma; however, following pathological examination, a diagnosis of osteosarcoma was confirmed. A total mandibulectomy was performed on the left mandible, with a fibular osteomyocutaneous flap used for reconstruction. At the 6-month post-operative examination, the patient demonstrated normal occlusion and oral commissure, and no recurrence or metastasis was observed over 2 years of follow-up.

“…Osteosarcoma of the jaw is associated with certain specific characteristics, such as a higher prevalence in the maxilla and male predominance. Wang et al reported that all maxillary de novo osteosarcomas arose from the alveolar ridge (5). The mass in the present case involved both the alveolar ridge and the body of the maxilla, possibly due to long-term growth leading to extension of the mass from the alveolar ridge to the body.…”

Abstract. Osteosarcomas of the jaw are comparatively rare and represent only 2-10% of all osteosarcomas. We herein present a rare case of an osteosarcoma exhibiting the radiographic and histological characteristics of cemento-osseous lesions in the alveolar ridge of the maxilla. A 53-year-old male patient presented with the complaint of gradual swelling of the left maxilla over 4 years. Radiography revealed an ill-defined radioopaque mass, intimately associated with the apices of the involved teeth, without a periosteal reaction. Microscopically, a cementicle-like structure was identified in the alveolar bone. In addition, the lesion exhibited typical characteristics of chondroblastic osteosarcoma in the body of the maxilla. The tumor contained abundant osteoid and cartilage intimately associated with anaplastic tumor cells. The cartilage displayed malignant-appearing cells in lacunae, and there was crowding at the periphery of the lobule where the spindle cells formed sheets. The differential diagnosis included primary osteosarcoma, concurrent cemento-osseous dysplasia and osteosarcoma, or a secondary osteosarcoma based on a pre-existing cemento-osseous lesion. The presence of the cementicle-like structure in the alveolar bone and the involvement of the periodontal ligament and alveolar bone proper were unique in our case. The general invasive growth pattern and the abundance of the irregular tumor bone helped establish the diagnosis of primary osteosarcoma. This case may represent evidence of the pathogenesis of primary osteosarcoma in the jaw.

Osteosarcoma of mandible – A case report with imaging perspective

Osteosarcoma (OS) is the most common primary bone malignant tumor in which osteoid is produced directly by malignant stroma as opposed to adjacent reactive bone formation. Osteosarcoma of the jaw (OSJ) represent less than 10% of all osteosarcomas and less than 1% of all malignant tumors of the head and neck. The dentist may be the first health care professional who observes tumors involving the jaws. Early diagnosis and radical surgery are the keys to high survival rates. Conventional radiographs are of limited value in head and neck osteosarcomas because of the superimposed bony structures. CT provides excellent detection of tumor calcification, cortical involvement, and, in most instances, soft-tissue and intramedullary extension. MR is even more effective in demonstrating the intramedullary and extra osseous tumor components on both T1-and T2-weighted images thus helps not only in better preoperative assessment but also post operative follow up. Hereby, reporting a case of osteosarcoma of mandible in a 40 year old female patient with emphasis on CT and MR imaging characteristics.
