A Case Report of Giant Cell Reparative Granuloma in the Nasal Cavity

Giant cell reparative granuloma (GCRG) is a rare benign fibrous-osseous neoplasm that mostly involves maxilla and mandible. Only a few cases of GCRG in the nasal cavity have been reported so far. Case Report: A 37-year-old man was referred to the otolaryngology clinic with the symptoms of left-sided nasal obstruction and bloody discharge since 3 years ago and proptosis since 3 months ago. CT-scan and MRI showed a heterogeneous mass with fluid-fluid level that had caused severe bony destruction. Biopsy confirmed the diagnosis of GCRG. Although GCRG is rare, its clinical and radiologic characteristics should be studied. This lesion should be considered in differential diagnosis when clinical data, CT-scan and MRI findings show a fibrous-osseous lesion in the nasal cavity.
