Plain radiographPlain radiographTumor effect to bone

- Purely lytic : geographic pattern

- Eccentrically located in the epiphyses and abut the subchondral bone

Bone response to tumor

- Expansile

- Margin

: Distinct or poorly outlined

: Classically nonsclerotic

: Erosion through the cortex

ClassificationClassification

- 15 % latent

- bone maintain normal contour

- Sharply defined margin

- 70 % active lesion

- deformity and expansion of bone

- cortical erosion

- Limited endosteal response

- 15 % aggressive lesion

- poorly outlined margin

- cortical breakthrough and soft tissue mass

- pathologic fracture

MRIMRI- To determine the extent of lesion both within the bone and the soft tissue

- Usually dark on T1-weight images and bright on T2 - weight images

PathologyPathology- Multinucleated giant cells ( 40-60 nuclei per cell) in a sea of mononuclear stromal cell

- Area of storiform spindle cell formation

- Small amount of bone or osteoid

CONCLUSION:CONCLUSION: • better functional result after curettage better functional result after curettage

and packing with cement than following and packing with cement than following wide resectionwide resection

• recommend curettage and cement recommend curettage and cement packing for giant cell tumor of bone packing for giant cell tumor of bone whenever it is technically feasiblewhenever it is technically feasible
