Figure 2: (a) Section showing numerous giant cells scattered amidst pleomorphic spindle cells (H and E, ×40) (b) section showing area of pseudopalisading necrosis (H and E, ×40) (c) section showing nuclear pleomorphism in spindle cells and bland nuclei in osteoclast-like giant cells, inset shows giant cell with 20–25 bland nuclei in giant cell (H and E, ×100) (d-f) immunohistochemical analysis showed that spindle cells are positive for vimentin (d), osteoclast-like giant cells are positive for CD68 (e), and both spindle cells and giant cells are negative for cytokeratin (f)
