Primarily it was considered the same as giant cell tumor (GCT) of the long bones but, later it was considered as to be a nonneoplastic, reactive lesion. The definitive etiology of CGCG is ambiguous, although trauma is considered as primary cause. Prevalent in age group younger than 30 years and shows more predilection for mandible. The clinical lesion presentation of central giant cell granuloma of the jaw ranges from localized lesion to wide aggressive lesion with destruction of adjacent bone.
