Adenomatoid Odontogenic Tumor: Clinical and Radiological Diagnostic Challenges


  • The University of the West Indies, Faculty of Medical Sciences, Kingston, 7, Jamaica


The adenomatoid odontogenic tumor (AOT) is a relatively uncommon odontogenic tumor with a relative frequency of 3–7%. The tumor is more common in females in their second decade of life. It exhibits a predilection for the maxillary anterior region. In this paper, we present a case of AOT in the mandible of a 27-year-old female. Histopathological examination of the tissue obtained from the initial incisional biopsy showed mostly an epithelial-lined cyst, which included a small nodule with the characteristic histological features of an AOT. Subsequent enucleation was done that confirmed the AOT diagnosis. The uncommon location of the lesion and the predominantly cystic configuration posed a clinical diagnostic challenge.
