Abstract
|
|
|
The ossifying fibroma have been considered a varient of fibrous dysplasia by many previous investigators due to their similarity of clinical and radiological features. The benign fibroosseous lesions including fibrous dysplasia, ossifying fibroma, and giant cementoma are quite similar and it was impossible to make a definitive diagnosis on clinical and radiological background.
Recently it was possible to, make a definitive pathologic diagnosis of these benign fibroosseous lesions.
The ossifying fibroma resembles fibrous dysplasia radiologically,. but histologically is characterized by osteoblasts and osteoclasts rimming spicules of bone within a fibrous stroma. The bone shows evidence of lamellar transformation.
The authors experienced a case of ossifying fibroma, uncommonly arising from the ethmoid, diagnosed by preoperative open biopsy and confirmed by final histopathologic examination, and obtained satisfactory result following surgical removal.
So, we report the case and reviewed the histological differential diagnosis of the ossifying fibroma and fibrous dysplasia with some literatures.
