Malignant tumours of the jaws

Area of Science:

• Oncology
• Oral and Maxillofacial Surgery
• Pathology

Background:

• Malignant primary and secondary bone tumors can manifest in the jawbones.
• Odontogenic carcinomas and sarcomas are rare neoplasms specific to the jaw.
• Non-odontogenic tumors, though more frequent overall, rarely occur in the maxilla and mandible.

Purpose of the Study:

• To review the occurrence and types of malignant bone tumors within the jaws.
• To differentiate between odontogenic and non-odontogenic tumors in this anatomical region.
• To highlight the relative frequency of primary versus secondary bone tumors in the jaws.

Main Methods:

• Literature review of malignant bone tumors in the jaw.
• Classification of tumors based on origin (odontogenic vs. non-odontogenic).
• Analysis of tumor frequency and location within the maxilla and mandible.

Main Results:

• The jaws harbor nearly all variants of malignant primary and secondary bone tumors.
• Odontogenic tumors are peculiar and uncommon to the jawbones.
• Osteosarcoma, Burkitt's lymphoma, and multiple myeloma are the most common primary jaw tumors.
• Metastatic tumors to the jaws are rare compared to other skeletal sites.

Conclusions:

• The jaws are a site for diverse malignant bone tumors, with specific odontogenic types being rare.
• Primary bone tumors like osteosarcoma are more prevalent in the jaws than metastatic disease.
• Understanding tumor patterns in the jaws is crucial for diagnosis and treatment.
