Table 2. Differential diagnosis of CGCT.

	Age	F to M radio	Predilection site	Multiple radio	Histopathology	Immunohistochemistry	Prognosis
CGCT	Neonate or newborn	9-10:1	Alveolar ridge	10% of case	Sheets and nests of large polygonal cells with demarcated cell membrane and granular cytoplasm. The nuclei are typically small, uniform, and pale staining, without evidence of mitotic activity	S100(-)	No recurrence and malignant transfer
GCT (2,16)	30 to 60 years old	2:1	Tongue	13% of case	Polygonal and abundant eosinophilic granular cytoplasm. The nuclei may be centrally or eccentrically located and are typically uniform, small, round, and pale-staining	S100(+); CD57(+); SOX10(+); CD68(+)	Rare recurrence and malignant transfer
