A Case Report on Bone Tumor: Osteosarcoma of the Maxilla of Mixed Type

Catherine Sullivan

Osteosarcoma (OS), which accounts for approximately 20% of all primary bone cancers, is the most prevalent primary malignant bone tumor. OS affects 2-4.8 out of 1,000,000 people annually and is more common in men (1.5:1) than in women. The femur (42%) is the most common site, followed by the tibia (19%), the humerus (10%), and the skull or jaw (8%) and the pelvis (8%) are other possible locations. We present a rare case involving a 48-year-old woman who presented with swelling of the left cheek and a palpable solid mass. A surgical biopsy confirmed the diagnosis of mixed type maxillary OS.
