[Oradlist] Question 2: Central Osteoma? Cone Beam images.

[Allan G Farman]

Ronnie, As a person who is actually registered as an Oral Pathologist in
one part of the world... as well as wearing the hat more commonly as an
Oral and Maxillofacial Radiologist, I have yet to see an osteoma show
any features of malignancy; indeed many lesions designated "osteomas" in
the frotal sinus can look surprisingly like cases of enostosis and
exostosis when found elsewhere. I guess that it is the generally benign
nature of these conditions that means that there has been a dearth of
detailed study regarding pathogenesis.

I guess for die-hard pathologists, then it becomes a matter of
nomenclature. 
The enostosis has its biological equivalent of the totally benign
exostoses. 
The typical ones that form on the "surface" (ie subperiosteal ) of the

mandible being the mandibular "tori"; very commonly spotted by a lot of

dentists. An osteoma, although by its very name a benign tumour, is
still a 
tumour. Of course the very scary thing being that, is there a tumour
that is 
totally benign. Kind regards,  Ronnie.

Allan: Since you ask... I attach a recent case of ivory osteoma that I
interpreted. There seem to be most common in the frontal and ethmoid
sinuses. Whether they differ biologically from enostosis is a matter
largely of conjecture. Best wishes, Allan

How could be the images of the central osteoma? Do you have a case?

Allan.
