Abstract
Introduction: Amongst all odontogenic tumors adenomatoid odontogenic tumor (AOT) accounts for only 3% of them. Being odontogenic in 1 origin, the tumor shows a plethora of histoarchitectural patterns. Sex predilection is towards females and likely occurs in second to third decades of life. Anterior maxilla is the commonest region for AOT; maxillary antrum being rare; in conjugation with dentigerous cyst (DC) then being the 2 rarest. Here we describe a case of gigantic AOT in 17-year-old male t Observation: hat occupied the left maxillary antrum with an impacted tooth which was clinically diagnosed as dentigerous cyst. In toto removal of the cystic tumor was accomplished with removal of retained impacted canine as well. Histopathological examination inferred the presence of an AOT with dentigerous like cystic lining. With uneventful healing no local recurrence was observed after 10 years of follow up. Implied take away lesson the Conclusion: prime importance of histopathological evaluation in all enucleated cysts, simultaneous more research into fourth type of a “hybrid variant” of AOT
