How to distinguish a benign from a malignant tumour in children and when should a biopsy be done and by whom

Area of Science:

• Pediatric Orthopedics
• Skeletal Oncology
• Pediatric Radiology

Background:

• Bone tumors are common in children, with a predominantly benign nature.
• Pediatric bone tumor incidence and types differ significantly from adult populations.
• Accurate differentiation between benign and malignant bone lesions in children is critical for appropriate management.

Purpose of the Study:

• To outline key clinical and radiological features for distinguishing benign from malignant bone lesions in pediatric patients.
• To guide orthopaedic surgeons in identifying concerning features that warrant referral to specialized oncologic centers.

Main Methods:

• Review of essential medical history components for pediatric bone lesions.
• Emphasis on critical physical examination findings in children with bone lesions.
• Discussion of characteristic radiological features differentiating benign and malignant bone tumors.

Main Results:

• Specific historical questions aid in assessing the risk of malignancy.
• Physical examination findings can suggest aggressive or benign processes.
• Radiological signs provide crucial clues for lesion characterization.

Conclusions:

• A systematic approach combining history, physical exam, and imaging is vital for evaluating pediatric bone lesions.
• Uncertainty regarding malignancy necessitates biopsy at a specialized pediatric tumor center.
• Timely and accurate diagnosis improves outcomes for children with bone tumors.
