Abstract:
Osteosarcoma is the most common primary malignant bone tumor, but only 5% of lesions occur in the jaws. The incidence of synchronous osteosarcomas (1% to 3%) is even less. A combination of synchronous osteosarcoma, with one of the lesions occurring in the jaws, is a very rare combination. A case of synchronous osteosarcoma with involvement of the mandible in a 16-year-old girl is reported. In addition to the mandible, lesions were identified in the left femur, sixth thoracic vertebra, and possibly in the lungs. Imaging and histopathological features are described.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
