Glandular Odontogenic Cyst is a relatively rare cyst of odontogenic origin, which shows glandular or salivary features that are thought to indicate the pluripotentiality of odontogenic epithelium. It is seen in middle-aged adults, and commonly involves the anterior region of the jaws, especially the mandible. It shows non-specific clinico-radiographic findings which may resemble other lesions, ...

The orthokeratinized odontogenic cyst is a relatively rare developmental odontogenic cyst of the jaws that occurs predominantly in males between the third and fourth decades. According to the 2005 World Health Organization's classification, orthokeratinized odontogenic cyst is not a part of the keratocystic odontogenic tumor spectrum. We present a case of a 41-year-old male with a history of re...

statement of problem: the aggressive nature and high recurrence rate of odontogenic keratocysts (okcs) may be due to unknown factors inherent in the epithelium or because of enzymatic activity in the fibrous wall. bcl-2 protein is characterized by its ability to inhibit apoptosis. purpose: the aim of the present study was to analyze the expression of bcl-2 protein in okcs and to compare it with...

The squamous odontogenic tumour is a rare benign neoplasm whose aetiology remains unknown. It usually appears in the jaw and its origin could be related to the ephitelial remnants of Malassez. Histologically comprises numerous islets of squamous, non-keratinized, well-differentiated and rounded epithelial cells a fibrous stroma without signs of atypical cells. There is a non-neoplastic lesion w...

The lining of an odontogenic cyst may show potential for neoplastic transformation to non odontogenic malignancies like squamous cell carcinoma and mucoepidermoid carcinoma and also odontogenic tumors like ameloblastoma and adenoamatoid odontogenic tumor (AOT). Unicystic ameloblastoma is a single cystic cavity lesion which shows ameloblastomatous differentiation in the lining. The clinical and ...

BACKGROUND The aim of this study was to determine the range of all histologically diagnosed odontogenic cysts along with age range, sex distribution and site of presentation over a 30-year period. METHODS All entries for odontogenic cysts occurring during 1975-2004 inclusive were retrieved and analysed for demographic data. RESULTS A total of 55,446 specimens were received, of these 7121 (1...

Calcifying odontogenic cyst is a developmental odontogenic cyst first described by Gorlin in 1962. It is considered as an extremely rare condition and shows extensive diversity in its clinicopathological appearances and biologic behavior. In this report a rare case of calcifying odontogenic cyst with ameloblastic proliferation (an extremely rare histologic variant) with one year follow – up is ...

BACKGROUND AND OBJECTIVE: Calcifying odontogenic cyst is an uncommon developmental cyst. It accounts for only 1% of jaw cysts and uncommonly occurs with odontoma. Herein, we report a case of calcifying odontogenic cyst, associated with complex odontoma. CASE REPORT: The patient was a 12-year-old girl with complaints of painless swelling in the mandibular first premolar. In radiographic examinat...

Adenomatoid odontogenic tumour (AOT) is a well-established odontogenic tumour with various clinicopathological variants. AOT quite frequently mimics an odontogenic cyst commonly a dentigerous cyst. Histologically a cystic component of AOT has been described in the literature. In the present paper we review the literature for the AOTs arising in an odontogenic cyst and add to the literature a ca...

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...
