Action
Obtain radiographs (strongly consider with chronic, focal symptoms)
Decision
Are the findings concerning for a malignant lesion?
Yes
- Discuss with orthopedic oncology and pediatric oncology
- Disposition pending specific lesion and consult recommendations
No
- Discuss with pediatric orthopedics; likely discharge
Background
Radiographic features of benign and malignant lesions (see Table 2, page 8 for additional details)
Benign:
- Well-defined margins
- Smooth, uninterrupted periosteal reaction
- Bone destruction confined to focal area of tumor
- Absence of soft-tissue mass
Malignant:
- Poorly defined borders
- Irregular, interrupted periosteal reaction
- Bone destruction is more widespread
- Presence of extraosseous extension or a soft-tissue mass outside of the bone
