Ameloblastomas in cats: a critical evaluation of the literature and the addition of one example.

The English language literature on feline ameloblastomas was evaluated. Seven acceptable cases were found and one additional example is added in this article. These rare tumors have occurred in cats over the age of 6 years, affected both sexes, both jaws, and various breeds. Two microscopic variants have so far been reported, namely the follicular pattern and the keratinizing pattern, which is similar to the keratinizing ameloblastoma in dogs. Ameloblastomas in cats have been confused in the past with two other feline odontogenic tumors: the inductive fibro-ameloblastoma (feline inductive odontogenic tumor) and the "calcifying epithelial odontogenic tumor" (amyloid-producing odontogenic tumor).
