Odontogenic tumors are lesions arising from or associated with odontogenic apparatus, their remnants or their derivatives. They are considered to be rare lesions, and as per the reported studies, they consist of 3%–9% of all biopsied specimens.[1‐13] The classification of odontogenic tumors is dynamic. It is modified regularly, as our understanding and perception of the nature and behavior of t...

Adenomatoid Odontogenic Tumor (AOT) is a well-established benign epithelial lesion of odontogenic origin. Rightfully called "the master of disguise," this lesion has been known for its varied clinical and histoarchitectural patterns. Not only does AOT predominantly present radiologically as a unilocular cystic lesion enclosing the unerupted tooth (which is commonly mistaken as a dentigerous cys...

A spontaneous ameloblastic fibroma was found in a 9-week-old guinea pig. Histopathologically, neoplastic cells consisted of two components: an odontogenic epithelium and odontogenic mesenchyme. The odontogenic epithelium formed strands, nests and islands that were interspersed within the odontogenic mesenchyme. In the marginal region, odontoblasts and scant dysplastic eosinophilic material were...

Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing od...

Pindborg or calcifying epithelial odontogenic tumor (CEOT) is a benign and noninvasive tumor that presents poor clinical features, a typical radiological picture and a characteristic histomorphology. CEOT is an uncommon odontogenic neoplasm, representing only 1% of all odontogenic tumors. The average age of occurrence is around 40 years with almost 1:1 gender ratio. It shows a mandible:maxilla ...

The adenomatoid odontogenic tumor (AOT) is usually an asymptomatic slow growth lesion. When grown, one can palpate a hard and large lesion. It is common for the tumor to cause shifting of neighboring teeth because tumor expansion is more common than teeth root resorption. Radiographically, there is a unilocular mass involving an unerupted tooth, sometimes opaque in the center and sclerotic in t...

odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. we previously described orosomucoid-1 protein expression in odontogenic myxomas. however, whether orosomuc...

Calcifying epithelial odontogenic tumor is a rare lesion. We report the imaging features of a calcifying epithelial odontogenic tumor. The imaging including conventional radiograph, CT and MR imaging revealed a well-defined lesion in the alveolar bone of the left maxilla, which contained an impacted tooth and some small radiopacities. CT and MR imaging demonstrated a contrast enhancement mainly...

Calcifying epithelial odontogenic tumor is rare. It may mimic both a non-odontogenic or odontogenic tumour causing expansion and destruction of the involved bones. Histopathology is the main stay for definitive diagnosis. Treatment options vary from enucleation to hemi mandibulectomy or maxillectomy followed by reconstruction. We present a young female patient with CEOT in an attempt to create ...
