Concurrent central odontogenic fibroma and dentigerous cyst in the maxilla: A rare case report

摘要

Central odontogenic fibroma (COF) represents a rare group of benign odontogenic tumor, while dentigerous cyst (DC), on the other hand, is the odontogenic cyst that encloses the crown of an unerupted tooth. A combination of COF and DC is rare and not reported in literature till date. The aim of this paper is to report a case of COF occurring concurrently with DC. The simultaneous occurrence of COF and DC raises the question of whether it is a collision tumor or their simultaneous occurrence is just a coincidence. In our case, the probable cause of simultaneous occurrence might be that COF would have displaced 23 resulting in the formation of DC.
