Summary
Multifocal giant-cell tumors are rare but present diagnostic and therapeutic challenges. These aggressive bone lesions require careful surgical management due to high recurrence rates.
Area of Science:
- Orthopedic Oncology
- Skeletal Pathology
Background:
- Giant-cell tumors (GCT) are typically solitary bone neoplasms.
- The occurrence of multiple distinct giant-cell tumors in a single patient is exceptionally rare, with only seven cases previously documented.
Observation:
- This study details eleven patients presenting with a total of thirty-five multifocal giant-cell tumors.
- Multifocal GCTs can be diagnostically challenging, mimicking primary tumors with metastatic spread, especially when lesions are not detected early or are metaphyseal.
- These tumors exhibit aggressive behavior, similar to solitary GCTs, posing significant therapeutic difficulties.
Findings:
- Multiple giant-cell tumors demonstrate aggressive clinical behavior.
- High recurrence rates are observed following curettage for multifocal GCTs.
Implications:
- Aggressive surgical intervention is crucial for managing multifocal giant-cell tumors.
- Distinguishing multifocal GCTs from metastatic disease is critical for appropriate treatment planning.
