Ten new cases of adenoameloblastoma were studied. Three were entirely extraosseous. Females predominated; age ranged from 9 to 16 years and the lesions were most often associated with an unerupted permanent maxillary anterior tooth. Painless swelling or missing teeth were the most frequent presenting symptoms for intraosseous lesions while peripheral lesions presented as painless gingival swellings. A well‐demarcated radiolucency containing faint radiopacities characteristically surrounded the crown and portions of the root. Simple enucleation was curative. Encapsulation, duct‐like structures containing eosinophilic hyaline material, spindled epithelium, cribriform pattern, microcyst formation, intraluminal calcification and dystrophic calcification of degenerated connective tissue were common histologic features. Results of special stains suggested possible connective tissue origin for the hyaline material. There were no clinical or microscopic similarities noted between the adenoameloblastoma and the simple ameloblastoma. “Odontogenic Adenomatoid Tumor” is suggested as a more acceptable designation.
