Giant cell reparative granuloma of nasal cavity, a case report.

Giant cell reparative granuloma (GCRG) is an unusual, nonneoplastic lesion affecting maxillary and mandibular bones. GCRG of the nasal cavity is exceedingly rare. To the best of our knowledge only few of such cases have been previously reported. Being a soft fleshy lesion of bone, it tends to have a benign course, not aggressive and it often recurs following incomplete excision. We report the case of a man with a GCRG of nasal cavity. We discuss the clinical presentation, differential diagnosis, histological evaluation and appearance on computed tomography and MRI.
