Bone Tumors

Bone tumors encompass a spectrum of neoplasms ranging from benign lesions like osteochondromas and osteoid osteomas to aggressive malignancies such as osteosarcoma, Ewing sarcoma, and chondrosarcoma, with biological behavior classified by features like margin definition, cortical integrity, and periosteal reaction patterns. Clinical significance lies in recognizing age-specific tumor predilections, understanding that night pain suggests malignancy while activity-related pain indicates benign processes, and appreciating that imaging characteristics such as sunburst periosteal reactions or moth-eaten destruction patterns guide differential diagnosis and urgency of intervention. For medical students, mastering the systematic approach to bone lesion evaluation through radiographic analysis, understanding biopsy principles to avoid compromising future surgical margins, and knowing that definitive treatment often requires multidisciplinary coordination between orthopedic oncology, medical oncology, and radiology is essential for appropriate patient management.
