Summary
Giant cell tumors of the bone are low-grade lesions often found in the hand. Tumor resection and bone grafting offer a favorable treatment outcome, preserving function while preventing relapse.
Area of Science:
- Orthopedic Oncology
- Skeletal Pathology
Background:
- Giant cell tumor of the bone (GCTB) is a neoplastic, low-grade lesion typically found in the epiphyseal or metaphyseal regions of long bones.
- GCTB accounts for approximately 19% of benign bone tumors and 9% of all primary bone tumors.
- Treatment strategies for GCTB remain controversial, with a need for radical yet function-preserving approaches.
Observation:
- Giant cell tumors predominantly affect the bones of the hand.
- These lesions are often solitary and become symptomatic upon significant bone destruction.
- The aggressive potential of GCTB necessitates its consideration in the differential diagnosis of hand tumors.
Findings:
- This study reports on three cases of GCTB presenting as lytic, expansive lesions in the hand.
- Treatment involved tumor resection followed by bone grafting to reconstruct the defect.
- All three patients experienced a favorable clinical course post-treatment.
Implications:
- Surgical resection combined with bone grafting appears to be an effective treatment for GCTB in the hand.
- This approach balances the need for radical tumor removal with functional preservation.
- Further research can validate these findings and refine treatment protocols for GCTB.
