A Case of Polyostotoic Fibrous Dysplasia

We report a 47-year-old woman with polyostotic fibrous dysplasia. She complained of a painless swelling of the left cheek since she was two years old. A craniofacial CT examination showed sclerotic changes of the left maxilla, sphenoid and temporal bone. Bone scintigraphy showed high uptakes at not only these craniofacial bones but also thoracic vertebrae, rib, left humerus and pelvis. A biopsy of the left maxilla bone was performed, and a histopathological examination showed fibrous dysplasia. Therefore, we diagnosed her as having polyostotic fibrous dysplasia. At present, the left maxillary tumor has not progressed. We are continuing careful follow-up.
