Odontogenic keratocyst (OKC) is one of the most aggressive odontogenic cysts owing to its relatively high recurrence rate and its tendency to invade adjacent tissue. Radiographically odontogenic keratocyst can be of different types – follicular, envelopmental, replacemental, extraneous and collateral.The biological behaviour, prognosis, recurrence and therapeutic approaches vary in different st...

OBJECTIVE This article presents the results of a retrospective study of the frequency and classification of odontogenic tumors recorded at four centers of diagnostic pathology in Rio de Janeiro, Brazil. STUDY DESIGN All medical records and microscopic slides of odontogenic tumor specimens for the years 1997 to 2007 were retrieved from the files of four services of diagnostic pathology in Rio ...

The purpose of this study was to evaluate the presence of M2-polarized macrophages and their relationships to angiogenesis in keratocystic odontogenic tumor (KCOT). M2-polarized macrophages were detected in KCOT samples by immunohistochemistry and immunofluorescence. Meanwhile, microvessel density measured with antibody against CD31 was closely correlated with the presence of M2-polarized macro...

An expansile lesion in the body of the left mandible had high attenuation (225 HU) on nonenhanced CT scans. Histologic examination revealed an odontogenic keratocyst with no evidence of mineralization or calcification within the lesion. The high attenuation was considered to be due to highly concentrated protein of thick, viscous keratin in the lumen of the keratocyst.

OBJECTIVE The aim of this systematic review was to assess the clinical and imaging findings of keratocystic odontogenic tumor (KOT). This article also attempts to determine the prevalence of KOTs and orthokeratinized odontogenic cyst (OOC) in the western Indian population and to compare demographic and radiographic findings of KOT of our cohort with that of the rest of the world.
