Traumatic giant cell tumor of rib: A case report

Figure 1 Chest X-ray findings. A: Initial chest film after the trauma revealed no fracture of the rib or mass lesion; B: Chest film at 3 mo after the trauma revealed a 5.1 cm, partially circumscribed mass-like opacity in the right lower chest wall, with adjacent rib destruction.

Figure 2  Chest computed tomographic scan showed a 5-cm tumor at the right anterior chest wall, with destruction of the right 6^th rib.

Figure 3  Whole-body bone scan showed increased uptake in the right 5^th to 7^th ribs.

Figure 4 Histopathology findings. A: Many osteoclast-like giant cells were distributed throughout the tumor, with scattered oval to spindle mononuclear cells in the background (hematoxylin and eosin); B: The mononuclear cells uniformly showed nuclear staining for H3F3A expression (immunohistochemical stain of H3F3A). Original magnification: × 400.
