“…OS is one of the most common malignant neoplasms of the jaw along with multiple myeloma and lymphoma, accounting for about 40%–60% of all primary malignancies of the jaws 8. Overall, the long bones of the limbs, predominantly in the knee region, are the most common site to be involved.…”

Ossifying fibroma is a type of fibro-osseous lesion categorised into cemento-ossifying fibroma and juvenile ossifying fibroma. Malignant transformation of fibro-osseous lesions is documented especially for fibrous dysplasia, but scarcity is seen when we search for malignant transformation of ossifying fibroma. Thus, we are presenting an extremely rare case of cemento-ossifying fibroma transforming into osteosarcoma with long sequential radiographic details.

“…It is the most common pathological subtype of OS, which represents 80% of all the cases. It is characterised by a high-grade malignant bone-forming mesenchymal neoplasm producing osteoid, high necrosis, and atypical mitosis [15,16], although, for diagnosis, evidence of bone or osteoid production by the tumour cells within the tumour is required. The radiographic appearance of COS is usually an osteolytic lesion with cortical destruction, and the tumour extends into surrounding soft tissues [14].…”

Osteosarcoma (OS) is a primary malignant bone tumour that usually occurs in children and adolescents. OS is a highly aggressive tumour type with a propensity for local invasion and systemic early metastasis to the lungs or other bones. According to the World Health Organization, there are different subtypes of OS, including conventional OS (osteoblastic, chondroblastic, fibroblastic), telangiectatic OS, low-grade OS, small-cell OS, parosteal OS, periosteal OS, and high-grade surface OS. In this mini review, we will discuss the background of OS and histopathological patterns and clinical behaviour of the disease. Understanding the subtypes of OS and their pathogenesis is crucial for developing more precise and effective therapies for OS patients.

Conventional osteosarcoma of the mandible: Report of a rare case

Abstract: Osteosarcoma of the jaw can be successfully treated by a single aggressive surgical operation with good prognosis. Timely diagnosis, with a complete surgical removal of the tumor with clear margins, can fulfill favorable clinical results.
