Adenomatoid Odontogenic Tumor of Maxillary Sinus – A Diagnostic Dilemma: Case Report and Brief Literature Review

Adenomatoidodontogenic tumor (AOT), constituting approximately 3-7% of all odontogenic tumors is described as a rare benign epithelial tumor of odontogenic origin. It is composed of odontogenic epithelium arranged in a variety of histoarchitectural presentations and closely resembles an ameloblastoma. AOT is mostly asymptomatic and is usually associated with impacted teeth in maxillary anterior region. We present a case of intraosseus follicular AOT existing in the maxillary sinus of a 14-year-old female child involving lateral incisor and canine impacted towards the orbital floor.The cystic tumor filled maxillary sinus and was removed along with the retained tooth. At one year follow up, healing was uneventful and no local recurrence was seen
