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...

Glandular odontogenic cyst (GOC) is a rare developmental odontogenic cyst of the oral cavity. The most common site of occurrence for GOC is a mandibular anterior region, presenting typically in the middle age and has a minor male predilection. This article presented a case of GOC and focused on the review of clinico-pathologic features of the lesions considered in the diff erential diagnosis. A...

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 ...

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 ...
