An osteosarcoma refers to a malignant primary bone tumor.
WHAT MAKES US SUSPECT IT?
- Tender soft tissue mass
- Absence of “constitutional symptoms”: no fever, weight loss, malaise, night sweats
- Alkaline phosphatase: elevated from increased turnover of damaged osteocytes
- Lactate dehydrogenase: elevated from increased turnover of damaged osteocytes
X-Ray imaging may reveal:
- Spiculated “sunburst” pattern
- Periosteal elevation (Codman triangle)
Most common primary bone tumor affecting children and young adults.
