El Fibroma Odontogénico Periférico fue definido por la OMS en el año 2005 como una neoplasia benigna rara constituida por tejido fibroso maduro y una cantidad variable de epitelio odontogénico inactivo. Dada su presentación clínica, localización y baja prevalencia suele ser mal diagnosticado como ...
Here is described a case of ameloblastic fibrosarcoma (AFS) affecting the posterior mandible of a woman who was treated surgically and recovered without signs of recurrence or metastasis after 12 years of follow-up. Tumor sections were immunostained for cell cycle, epithelial and mesenchymal markers. Imm...
Abstract The aim of this study was to evaluate the immunoexpression of glucose transporters 1 (GLUT-1) and 3 (GLUT-3) in keratocystic odontogenic tumors associated with Gorlin syndrome (SKOTs) and non-syndromic keratocystic odontogenic tumors (NSKOTs), and to establish correlations with the angiogenic in...

The radiographic features of an intraosseous lesion are usually associated with the biological behavior of the tumor. In view of the fact that the growth and behavior of keratocystic odontogenic tumors (KCOT) is mainly associated with the proliferation of the cystic epithelium, the objective of the prese...
Alterações degenerativas e metaplásicas são usualmente observadas no revestimento epitelial dos cistos odontogênicos. Nos tumores odontogênicos estes processos são considerados mais raros. Objetivo: demonstrar a presença de células claras no revestimento epitelial de uma série de lesões odonto...
