INTRODUCTION — Prior to the development of modern cardiovascular surgery, most cases of mediastinitis arose from either esophageal perforation or from contiguous spread of odontogenic or retropharyngeal infections. Rarely, primary infections of the mediastinum developed as a result of penetrating trauma or hematogenous spread of infection. However, in modern practice, most cases of mediastiniti...

Odontogenic myxoma represents an uncommon benign neoplasm comprising of 3–6% of all odontogenic tumors.This articles presents a rare case of odonogenic myxoma occurring in the mandible with a brief overlight on its etiology,immunocytohistochemistry,radilogical and treatment fetaures of odontogenic myxoma. keywords: odontogenic myxoma,fibro-myxoma,odontogenic tumours

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...

In this study, we compared mast cell tryptase and CD31 expression between odontogenic tumors with the aim of predicting the clinical behavior of these lesions at the time of initial biopsy. We also evaluated the correlation between mast cell tryptase and CD31 expression to clarify the role of mast cells (MCs) in the growth of odontogenic tumors. Immunohistochemical staining with anti-MC tryptas...

Odontogenic lesions can be divided discretely into cysts (an epithelial lined pathological cavity) and tumors (a solid tissue mass, not necessarily neoplastic). They are derived from tooth forming tissues, either the epithelial or the ectomesenchymal or both. They form a heterogeneous group of hamartomatous lesions, benign and malign tumors. According to their origins, they are divided into epi...

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 ...

OBJECTIVES Odontogenic tumours comprise a large heterogeneous group of lesions originating from odontogenic epithelium and/or ectomesenchyme and its vestiges. The aim of this study was to analyze odontogenic tumours in children and adolescents seen at a tertiary institution in South Western Nigeria and compare with results from previous studies. MATERIAL AND METHODS Archival records of the De...
