Keratinizing ameloblastomas

Letters to the Editor GP FUNDHOLDER

LIST

KERATINIZING AMELOBLASTOMAS

Sir,

Sir:

At the Royal London Hospital, with the assistance of our Contracts Department WChave collated a list of procedures from the fundholder list which is now being distributed to fundholders along with the DOH list for their Specialties. May I suggest this as a template which might be used by other Units. See the Table below.

The tumours described by Siar and Ng’ in the Journal as reprcscnting either combinations of amcloblastoma and odontogcnic keratocyst or kcratinizing ameloblastomas are interesting and unusual. However: I believe that their second suggestion that the tumours are simply unusual keratinizing ameloblastomas is the appropriate conclusion from the evidence that they present. I see no reason why some epithelial islands in such lesions could not resemble odontogenic kerdtocysts but I hesitate to conclude that their doing so implies a combined ameloblastoma and an odontogenie keratocyst. Incidentally. canine amcloblastomas often exhibit abundant keratinizdtion,2*3 although it is rare in human ameloblastomas.
