Abstract
Adenomatoid odontogenic tumor (AOT) is an uncommon benign tumor of odontogenic origin composed of odontogenic epithelium in a variety of histopathological patterns. Recently, the WHO classification of odontogenic tumors has been revised and few changes have been made. According to WHO, the AOT is reclassified as an epithelial odontogenic tumor. Very few cases of AOT associated with a dentigerous cyst have been reported in the available literature. We present an additional case of an AOT arising from a dentigerous cyst around the crown of an unerupted lower canine in a 12-year-old boy, which was clinically diagnosed as a dentigerous cyst. Histologically, our case showed ‘odontoma-like’ areas which have been described in only two other previous case reports. We believe that this case represents an odontogenic cyst with neoplastic change containing both epithelial and mesenchymal components. Further studies to determine whether the AOTs derived from an odontogenic cyst could represent a distinct ‘hybrid’ variant (different from the three variants described so far) are to be done.
