Central odontogenic fibroma of maxilla: A case report

Central odontogenic fibroma is a rare mesenchymal odontogenic neoplasm with a prevalence of 0.1 of all odontogenic tumors. Herein we present a case of a 63-year-old female with swelling in the left posterior maxillary region which was later diagnosed as a central type of odontogenic fibroma. A painless swelling was noted in the left maxillary tuberosity area. Orthopantamogram was advised which revealed a unilocular lesion with a mixed radiopaqueradiolucent appearance. This was associated with a spherically dense radiopaque mass in the left maxillary sinus region. A provisional diagnosis of the calcifying epithelial odontogenic tumor was made. An incisional biopsy was done and the specimen was sent for histopathological evaluation. The microscopic examination revealed inactive-looking odontogenic islands in the background of mature connective tissue stroma. Few foci of calcifications were also noted. After contemplating all the histological features a final diagnosis of central odontogenic fibroma was given. This case emphasizes the importance of histopathological examination of the unusual and rarely observed central odontogenic fibroma which can be missed due to similarities with other entities.nbsp
