Management of a rare giant cell tumor of the distal fibula: A case report

Figure 1 Radiographs showed expansile lesion with soap bubble appearance.

Figure 2 Computed tomography showed the distal lateral cortex of the fibula was invaded.

Figure 3 Magnetic resonance imaging scan showed soft tissue around the lateral malleolus was also invaded.

Figure 4 Pathologically, the tumor comprised mononuclear stromal cells and multinuclear giant cells. Original magnification: × 100.

Figure 5 The macroscopic piece for the tumor: fragile, yellowish-brown tumor tissue. A: Tumor in vivo; B: Tumor in vitro; C: Macroscopic bisection of tumor (yellow circles indicates the bone cement).

Figure 6 Postoperative X ray showed the tibial talar joint was secured with three screws.

Figure 7 X-ray 2 years after the operation showed osseous fusion of the tibial talus joint.
