Giant cell granuloma is a rare tumor of paranasal sinuses. Generally, it occurs at young ages, with a 4th decade peak. It is mostly seen in the premolar teeth area. This tumor tends to locate at the mandibular, maxillary, and ethmoid sinuses. Giant cell granuloma generally occurs after a trauma. Reparation of the lesion is a bone reaction, which can not be controlled. As for pathologic findings, it is met with giant granuloma cells mixed up in cells, like stroma spind gland. Varied vascularity, hemorrhage, and inflammation draw attention. We try to discuss a case of giant cell reparative granuloma of the nasal cavity by expansing inferior concha to superomedial at the right nasal cavity that originated from the right maxillary sinus, growing after trauma.
