Adenomatoid odontogenic tumor is a relatively uncommon distinct odontogenic neoplasm. It is an uncommon tumor of odontogenic origin with varying number of ductlike structures and inductive changes in the stroma. It is a benign and slow growing epithelial tumor and represents 3% of all odontogenic tumors. Its occurrence is more common in anterior region of the maxilla than mandible. Most of the ...

This case report describes a rare case of an adenomatoid odontogenic tumor (AOT) arising in the mandibular third molar region of a 20-year-old female. The tumor was a well-circumscribed intraosseous lesion with an embedded tooth. Histologically, the induction of extensive globular calcification was evident in addition to the characteristic histological features of AOT. The present case lends su...

The odontogenic fibroma is a rare, benign tumor of mesodermal origin, and one of the most ill-defined and least understood of all odontogenic neoplasms. 1 It presently is thought to originate from either dental follicle, periodontal ligament, or dental papilla. 2 Bhaskar reported the lesion as being the most common odontogenic tumor comprising approximately 23°70 of all odontogenic lesions. 3 T...

Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differ...

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, constituting only 3% of all odontogenic tumors. AOT is characterized histologically by the formation of duct-like structures with amyloid-like deposits. An 18-year-old male presented with right chek swelling. CT scan revealed well-defined expansile heterogeneous mass with central hypodensity. Patient underwent excis...

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm which was first described by Pindborg in 1955 representing only 1% of all odontogenic tumors. The tumor has an ectodermal odontogenic origin. This tumor are considered benign but can be locally aggressive in nature with recurrence rates of 10-15% reported. Surgical treatment varies from simply enucleation t...

OBJECTIVE Determine survival and factors affecting survival for patients with malignant tumors of odontogenic origin. STUDY DESIGN Retrospective analysis of the National Cancer Institute's SEER database (Surveillance, Epidemiology, and End Results). SETTING Tertiary medical center. SUBJECTS AND METHODS All cases of malignant tumors of odontogenic origin were extracted from the SEER databa...

The aim was to review previous cases of Odontogenic Keratocyst or Keratocystic Odontogenic Tumor according to the new WHO classification. We used all cases diagnosed as Odontogenic Keratocyst or Keratocystic Odontogenic Tumor registered in the archives of the Pathologic Anatomy Laboratory of the Department of Pathology and Oral Diagnosis of the School of Dentistry of the Federal University of R...

PURPOSE Multicystic ameloblastoma is a benign epithelial odontogenic tumor that exhibits a more aggressive behavior than follicular cyst and keratocystic odontogenic tumor (KCOT). The aim of this study was to perform an immunohistochemical evaluation of the mean microvessel density (MVD) effect on clinical behavior of odontogenic lesions and to determine whether peritumoral or intratumoral MVD ...
