Abstract
Giant cell reparative granuloma (GCRG) is an unusual, non-neoplastic fibrous lesion that most often arises in the mandible and maxilla. A differential diagnosis has to be made with that of other osteolytic tumors (giant cell tumors, odontogenic tumors, fibrous dysplasia, etc).
We report on one case with a large GCRG in the maxillary sinus. The patient was a 41-year-old man who came to our department complaining of swelling on the right side of his face. A computed tomography examination showed an expansive mass occupying the right maxillary sinus with some destruction of the orbital floor. The mass included osteoplastic and osteolytic lesions. Biopsy specimens suggested GCRG. The patient received surgical resection, which was followed with an injection of corticosteroids.
We discuss clinical characteristics, differential diagnosis, histological evaluation, and treatment options of GCRG.
