title: Giant cell reparative granuloma originating from the ethmoid sinus.
abstract: Giant cell granuloma is a reactive osseous proliferation and is histologically benign despite its aggressive clinical course. It usually involves the maxilla and the mandible in the region of the head and neck. It is rare in the ethmoid region. In this paper, an aggressive and recurrent giant cell reparative granuloma, which is recurred in a very short time period, originating from the ethmoid sinus is presented and the criteria for the differential diagnosis are noted in the light of the histological, clinical and biochemical parameters and the literature is reviewed.
