Giant cell tumors (GCTs) and giant cell granulomas (GCG) differ in the nuclear count of their giant cells. In GCTs, the giant cells have numerous nuclei (50-80), whereas in GCGs, the giant cells have fewer nuclei (3-20). Other features listed, such as uniform distribution, presence of inflammatory cells and IL, and small foci of spindle-shaped cells, can be similar in both conditions.
