Although rare, hard tissue deposits, namely dystrophic calcifications and cartilage, have been reported to occur in the connective tissue wall of the odontogenic keratocyst. However, dentinoid formation has not been previously documented. A case involving the left mandibular premolar-molar region in a 37-year-old Malay male is described here along with a brief review on the reported prevalence ...

Calcifying odontogenic cyst (COC) is an odontogenic cyst with accumulation of ghost cells that has central and peripheral subsets. Here, we present an 11-year-old male patient with an intraoral swelling on the left posterior mandibular ridge interfering with eruption of the second molar. Histopathologic examination revealed a cystic lesion lined by ameloblast-like epithelium in the basal layer ...

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third...

The purpose of this study was to investigate a case of calcifying odontogenic cyst (COC) in which numerous calcifications were observed not only in the lining epithelium, but also in the cyst wall, using cytokeratins 13 (CK13), 19 (CK19), and core binding factor a-1 (cbfa-1) as primary antibodies. Cells of Malassez's epithelial rest were stained as controls. Cells of the epithelial nests in the...

Background. The aim of this study was to investigate myofibroblast (MF) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of MFs and the clinical behavior of these lesions. Methods. A total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (UAM), solid ameloblastoma (SA), odontogenic keratocyst (OKC), dentigerous cyst (DC), rad...

Introduction: Calcifying odontogenic cyst (COC) is a benign cystic type of tumor, without neoplastic character and unusual in nature. Its development slow asymptomatic, being characterized by mass that affects the maxilla mandible. Case Report: A 40-year-old male presented with mild extra intraoral facial swelling region right upper incisors, symptoms. On examination, he observed intact normal ...
