Abstract
The adenomatoid odontogenic tumor (AOT) has a prevalence of 3% to 7% among odontogenic tumors and 3 described variants: Follicular, extrafollicular, and peripheral (or gingival). We reported a case of extrafollicular AOT in a 31-year-old melanoderm woman. An increase in volume was observed in the lower left third of the face associated with bulging of the buccal and lingual cortices in the region of elements 34 to 32. The imaging revealed a well-defined unilocular radiolucent area with sclerotic margin, involving periapices of elements 34, 33, and 32, rupture of the vestibular bone cortex in the region, and mild root resorption of units 33 and 32. Histopathologic examination revealed presence of fibrovascular capsule and epithelial cells forming structures such as ductus and solid patter. The treatment was an excisional biopsy. Follow-up of 7 and 15 days with satisfactory postoperative period was performed. Provision will be made every 6 months.
