The lesion traditionally known as odontogenic keratocyst has been renamed by WHO in 2005, as “keratocystic odontogenic tumor” as it is more appropriate and reflects its potential for local, destructive behavior. It is a benign intraosseous neoplasm of jaw, which is unusual due to its characteristic histopathological and clinical features, including potentially aggressive behavior, high recurren...

Calcifications or hard tissue deposits in the wall of keratocystic odontogenic tumor (KCOT) are rare and uncommon. Three types of calcifications have been reported in the literature: dystrophic, cartilagenous, dentinoid. A case of maxillary KCOT with calcification is reported with a review on prevalence and pathogenesis of these calcifications. The calcifications associated with the connective ...

The term odontogenic keratocyst was first used by Philipsen in the year 1956. The lesion was renamed by him as keratocystic odontogenic tumor (KCOT) and reclassified as odontogenic neoplasm in the World Health Organization's 2005 edition that occurs commonly in the jaws having a predilection for the angle and ascending ramus of mandible. In contrast, KCOTs arising in the maxillary premolar regi...

Inclusion bodies are nuclear or cytoplasmic aggregates of proteins that may be formed due to infections or genetic disorders. Asteroid body is one such inclusion that is eosinophilic and spider like that are usually found in infections like sarcoidosis and sporotrichosis. Inclusions are usually pathognomonic of certain diseases and conditions, navigating the pathologist to arrive at a diagnosis...

PURPOSE Multicystic ameloblastoma is a benign epithelial odontogenic tumor that exhibits a more aggressive behavior than follicular cyst and keratocystic odontogenic tumor (KCOT). The aim of this study was to perform an immunohistochemical evaluation of the mean microvessel density (MVD) effect on clinical behavior of odontogenic lesions and to determine whether peritumoral or intratumoral MVD ...

Keratocystic Odontogenic Tumor has been defined by the World Health Organization as a benign intraosseous neoplasm of odontogenic origin with characteristic lining of the parakeratinized squamous epithelium. Due to variable features of this lesion pertaining to clinical and biologic behaviour, this tumor is been studied extensively even today with respect to its molecular aspects to resolve man...
