Adenomatoid odontogenic tumorlike lesion in a male Wistar rat.
An odontogenic tumor in the maxilla of a male Wistar rat is described. The tumor consisted of large epithelial areas with peripheral palissading and with juxtaepithelial material resembling dentin. The neoplastic odontogenic epithelium seems capable of inducing peridental mesenchyme to form a kind of dental hard tissue normally not present at that site.
