Resumo: The adenomatoid odontogenic tumor (AOT) is a benign neoplasm of odontogenic epithelial origin. The objective of this research was to evaluate the clinical, radiographic and histopathological characteristics of 20 cases of AOT. Clinical and radiographic data were collected from the patient's files recorded over a period of 17 years. Age, sex, race, location, size, duration of the lesion, AOT variant, radiographic aspects of density, locularity and edges; and detailed histopathological features were analyzed. Sixteen patients (80.0%) were female and 4 (20.0%) were male, with a mean age of 22.7 years. All lesions were intraosseous and affected the maxilla (70.0%) and mandible (30.0%), with a mean size of 39.4 mm and a mean injury duration of 14.8 months. Twelve tumors (85.7%) were follicular and 3 (14.3%) were extrafollicular. Five patients presented pain (31.3%). Microscopically, 12 cases showed a predominantly solid pattern (60.0%), three predominantly cystic (15.0%) and five (25.0%) without predominance. Classic histological patterns were identified in the following proportion in the cases: solid nodules (95.0%), lace-like cords (90.0%), rosettes (90.0%), duct-like structures (90.0%) and areas of mineralization (80.0%). The clinical, radiographic and histopathological characteristics in this case series from Brazil are similar to the findings in other populations.
