Abstract
Odontogenic fibroma (OF) is a rare benign odontogenic neoplasm that is most commonly found in the mandibular/premolar region of female patients in the second to fourth decades of life. Well-defined radiolucent lesions that may induce root resorption are normally observed. Rare variants of OF have been described in the prior literature, including references to: 1) giant cell lesions, 2) amyloid-like protein deposition, and 3) ossifying variants. Immunohistochemistry can contribute to understanding the biological behavior and the pathogenesis of OF. Therefore, this case report aimed to describe a new case of ossifying OF and discuss the histopathology and immunohistochemical features. Key words:Odontogenic fibroma, jaw tumors, ossifying variant.
Highlights
Odontogenic fibroma (OF) is a rare benign odontogenic neoplasm
The cytokeratin (CK) expression may well be a useful tool to confirm the diagnosis of OF in epithelium-poor cases and to reveal the main types expressed in the OF when compared to other odontogenic tumors [3]
The present study is aimed to describe a rare case of ossifying odontogenic fibroma and discuss the histopathology and immunohistochemical features of this rare variant of OF
