NCIt definition : A slow growing, locally invasive neoplasm arising from tooth-forming tissues. It most
often grows intraosseously in the mandible and less frequently in the maxilla. In
a minority of cases it grows extraosseously in the gingiva. It is characterized by
the presence of a fibrous stroma, epithelial cells with abundant eosinophilic cytoplasm,
and amyloid material which is often calcified. Small tumors may be successfully treated
with enucleation. Local resection is usually required for larger tumors. Recurrences
have been reported in a minority of cases.;
