Maxillary adenomatoid odontogenic tumor associated with a premolar.

Kalia V, Kalra G, Kaushal N, Sharma V, Vermani M - Ann Maxillofac Surg (2015 Jan-Jun)

Bottom Line: Consequently, the WHO (2005) classification of odontogenic lesions considered this process to represent a mixed odontogenic neoplasm.We present a case of a 12-year-old female patient with an AOT of diameter 5 cm × 5 cm located in the anterolateral region of the maxilla in association with an impacted premolar tooth.The rarity of AOT, association of this lesion with regards to maxillary premolar, the exaggerated size at presentation, the eruption of the displaced canine postoperatively and uneventful healing of the bony defect without adjunctive therapy makes this case unique.

ABSTRACT
The adenomatoid odontogenic tumor (AOT) represents 3-7% of all odontogenic tumors, and over 750 cases have been reported in the literature. This lesion was formerly considered to be a variant of the ameloblastoma and was designated as adenoameloblastoma. These lesions may infrequently produce dentinoid material and rarely enamel matrix. Consequently, the WHO (2005) classification of odontogenic lesions considered this process to represent a mixed odontogenic neoplasm. We present a case of a 12-year-old female patient with an AOT of diameter 5 cm × 5 cm located in the anterolateral region of the maxilla in association with an impacted premolar tooth. The rarity of AOT, association of this lesion with regards to maxillary premolar, the exaggerated size at presentation, the eruption of the displaced canine postoperatively and uneventful healing of the bony defect without adjunctive therapy makes this case unique.

Figure 2: Preoperative orthopantomograph

Mentions: The orthopantomography (OPG) revealed [Figure 2] a radiolucent lesion with irregular borders located between the apices of the left maxillary lateral incisor and the left maxillary second premolar. The canine was displaced toward the apices of the incisors, and the first premolar tooth was present within the lesion. The coronal computed tomography (CT) of the maxilla revealed a well-circumscribed radiolucent mass with calcific bodies which were multiple and interspersed throughout the lesion with prominent sclerotic margins. Maxillary left canine was impacted without being involved in the lesion. The axial CT confirmed that the left maxillary sinus and the nasal cavity were not encroached. Maxillary left first premolar was present within the lesion [Figure 3].
