Objective: The aim of the study is to update our understanding clinicopathological features odontogenic keratocysts in a series 43 cases from single center.Material and Methods: This retrospective included 51 specimens patients diagnosed between 2010 2020. Microscopic findings, patients’ age, gender, lesion location, presence or absence recurrence were noted.Results: group 22 men 21 women with ...

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity with or without luminal and/or mural tumor growth. It accounts for 5 to 15% of all intraosseous a...

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...

The term Unicystic Ameloblastoma (UA) refers to those cystic lesions that show clinical and radiological characteristics of an odontogenic cyst but on histological examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. Till date, lot of controversies exist among oral surgeons and oral pathologists regarding this...

Histological evaluation revealed multiple fragments of richly cellular mesenchymal tissue containing round droplike islands and long narrow anastomosing cords of odontogenic epithelium. The epithelial islands and cords were characterized by peripheral columnar or cuboidal hyperchromatic cells and were frequently only two cell layers thick (Fig. 2). The mesenchymal component contained evenly dis...

The glandular odontogenic cyst is a cyst that arises in development sites of the teeth; it is usually found in the mandible and maxilla,1 and is characterized by cuboidal or columnar epithelium on the surface and in crypts within the epithelium. This cyst generally is encountered in the anterior areas of the mandible; it is more common in adults aged over 40 years, and tends to recur. The recor...

Background Ameloblastoma is the most frequently encountered neoplasm arising from the odontogenic epithelium. Beclin-1 protein plays a critical role in autophagy as a tumor suppressor gene. Whereas, the Murine Double Minute 2 (MDM-2) is a cellular proto-oncogene capable, if amplified, of causing tumor-genesis. The expression & prognostic significance of both genes are largely unexplored, yet, i...

Ameloblastic fibrodentinoma (AFD) is considered a mixed odontogenic tumor that is characterized by conserved epithelial and ectomesenchymal neoplastic components. AFD is composed of long narrow cords and islands of odontogenic epithelium; the epithelial strands lie in a myxoid cell-rich ectomesenchymal tissue with stellate-shaped fibroblasts that exhibit long slender cytoplasmic extensions that...

An 11-year-old girl presented to our department to have a second opinion regarding a lesion involving her left mandible. She had previously undergone several radiographic exams including panoramic, helical, and cone-beam computed tomography. Radiographic examinations revealed a well-defined radiolucent region, which contained an irregular radiopaque mass of 3 cm in diameter, localized to the le...
