Primordial odontogenic tumor: An immunohistochemical profile

Primordial odontogenic tumor: An immunohistochemical profile

BACKGROUND Primordial Odontogenic Tumor (POT) is a recently described odontogenic tumor characterized by a variably cellular loose fibrous tissue with areas similar to the dental papilla, covered by cuboidal to columnar epithelium that resembles the internal epithelium of the enamel organ, surrounded at least partly by a delicate fibrous capsule. The purpose of this study was to investigate the...

Follicular adenomatoid odontogenic tumor: immunohistochemical study.

Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic lesion that affects young patients, with female predominance, mainly in second decade, showing a radiolucent unilocular image associated with an unerupted tooth, usually a canine. In spite of previous and confusing denominations, such as adenoameloblastoma or adenomatoid ameloblastic tumor, AOT is a benign tumor with a very l...

Primordial Odontogenic Tumor of Mandible; A Case with Proposed Diagnostic Criteria

Comparative immunohistochemical study of Bcl-X in ameloblastoma, keratocystic odontogenic tumor and adenomatoid odontogenic tumor

OBJECTIVES Since its recognition as a physiologic process associated with tumor, among molecular mechanisms involved in tumor progression, defects in regulation of apoptosis have generated an accelerating volume of research that has sought to elucidate the role of programed cell death in pathogenesis and treatment of various tumors. Therefore, this study was performed to understand better the d...

Mural squamous odontogenic tumor in a primordial cyst.

An additional case of mural squamous odontogenic tumor in a mandibular primordial cyst is reported and its clinicopathologic features are described. Introduction Since Pullon et al.[1] reported 6 cases of a previously undescribed lesion under the name squamous odontogenic tumor (SOT) in 1975, SOT has been accepted as a distinct entity among odontogenic tumors [2,3]. Histologically identical les...
