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: The adenomatoid odontogenic tumor (AOT) represents 3-7% of all odontogenic tumors, and over 750 cases have been reported in the literature.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.

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 1: Preoperative intraoral picture

Mentions: On extraoral examination, there was a swelling on the left side of the face causing obvious asymmetry with obliteration of nasolabial sulcus. Intraorally, there was an expansion in all dimensions measuring about 5 cm × 5 cm in anteroposterior and superior inferior direction. On palpation, the swelling was hard, nonlobulated; nontender, not fixed to the overlying skin and local temperature was not raised. The growth had expanded the palatal, alveolar and buccal aspect to such an extent that the overlying mucosa had indentation marks from the lower teeth causing discomfort to the patient during speech and mastication [Figure 1].
