the term odontoma is used to identify a tumor that is characterized by the production of mature enamel, dentin, cementum and pulp tissue and may interfere with the eruption of the associated tooth. the present report describes an odontoma in a 13-year-old boy, which is associated with an impacted tooth through a canal

calcifying epithelial odontogenic tumor (ceot) is a rare benign, but locally infiltrating odontogenic neoplasm. it accounts for less than 1% of all odontogenic tumors. this is a case report of recurrent ceot in the maxilla. a 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. it is of particular concern because of its anatomic location in the m...

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumour...

calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

background: solid ameloblastoma (sab) is an invasive tumor which infiltrates adjacent normal tissues. adenomatoid odontogenic tumor is a noninvasive tumor and never infiltrates surrounding normal tissues. the purpose of this study was to determine the biological behavior of these two epithelial odontogenic neoplasm by detecting ki-67 and bcl-2, which are mitotic and anti apoptotic markers respe...

A systematic review of the literature from 1993 to 2011 was undertaken examining frequency data of the most common odontogenic cysts and tumors. Seven inclusion criteria were met for the paper to be incorporated. In the preliminary search 5231 papers were identified, of these 26 papers met the inclusion criteria. There were 18 297 odontogenic cysts reported. Of these there were 9982 (54.6%) rad...

UNLABELLED The practice of pathology is currently undergoing significant change, due to advances in the field of molecular pathology. Tumor markers are molecules that help the pathologists for confirmatory diagnosis of histopathologically confounding lesions. Odontogenic tumors are relatively rare with estimated incidence of less than 0.5 cases/ 100,000 population per year. Odontogenic tumors c...

Introduction: squamous odontogenic tumor is a rare benign locally infiltrative odontogenic tumor of epithelial origin and only a few cases, less than 50, have been reported in literature. the challenge is in diagnosing the tumor is due to its close resemblance to acanthomatous ameloblastoma and well differentiated squamous cell carcinoma. case report: Herein we report, not previously reported, ...
