Genetic Changes in Sporadic Keratocystic Odontogenic Tumors (Odontogenic Keratocysts)

Journal of Dental Research, 2007
Little is known about the genetic background of keratocystic odontogenic tumors (KCOT, odontogenic keratocysts). Our aim was to characterize genomic aberrations in sporadic KCOT using cDNA-expression arrays and array-comparative genomic hybridization. For cDNA-expression arrays, 10 KCOT specimens and 20 fetal tooth germs were studied. Quantitative real-

Significance of Podoplanin Expression in Keratocystic Odontogenic Tumor

Journal of Oral Pathology and Medicine, 2010
The most important clinical features of the keratocystic odontogenic tumor (KCOT) are its potential for locally destructive behavior, a tendency to recur, and its origin in the odontogenic epithelium. The clinical features of KCOT are similar to those of ameloblastoma (AM).

CEA immunoreactivity in odontogenic tumors and keratocysts

Oral Surgery, Oral Medicine, Oral Pathology, 1988
Forty-five oral tumors and cysts were stained immunohistochemically for the presence of carcinoembryonic antigen (CEA). CEA, or a CEA-like antigen that is not nonspecific cross-reacting antigen (NCA), was demonstrated in the majority of aggressive or malignant tumors showing squamous differentiation, including cases of ameloblastoma, odontogenic ...

The odontogenic keratocyst: A benign cystic tumor?

Journal of Oral and Maxillofacial Surgery, 1984
Three hundred nineteen odontogenic keratocysts from 255 patients (167 males and 88 females, a 2:1 ratio) were histologically and clinically examined. The cysts sometimes occurred as multiple or recurrent lesions or in association with Gorlin's syndrome. The rate of recurrence for the total population was 27%.

[Studies on keratocystic odontogenic tumors].

Beijing da xue xue bao. Yi xue ban = Journal of Peking University. Health sciences, 2010
Keratocystic odontogenic tumors (KCOTs, previously known as odontogenic keratocysts) are aggressive, noninflammatory jaw lesions with a putative high growth potential and a propensity for recurrence. This article puts together a summary of the serial studies related to KCOTs undertaken by the author's research group in recent years.

Immunolocalisation of laminin-1 in keratocystic odontogenic tumors

Acta Histochemica, 2010
Keratocystic odontogenic tumors (KOTs) are distinct odontogenic lesions frequently affecting the jawbones. They may be associated with nevoid basal cell carcinoma syndrome (NBCCS), and may exhibit disorders involving the extracellular matrix. The aim of this study was to investigate the immunolocalisation of laminin-1 in 20 cases of KOTs in order to ...

Pattern of recurrence of nonsyndromic keratocystic odontogenic tumors

Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, 2016
To describe and analyze recurrent pattern of KOTs according to time.This retrospective chart study evaluated histologically confirmed nonsyndromic keratocystic odontogenic tumors (KOT) treated at our institutions between 1975 and 2012.Mean age at time of diagnosis was 48 years, and male/female ratio was 1.8:1.

[The odontogenic keratocyst--odontogenic cyst or benign tumor?].

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia, 2005
The odontogenic keratocyst is the third most common cyst of the jaws, after the follicular and radicular cyst. Keratocysts most commonly occur as single lesions in the jaw of otherwise healthy persons. Multiple odontogenic keratocysts are a well-recognized feature of the nevoid basal cell carcinoma syndrome.

Multilocularity as a Radiographic Marker of the Keratocystic Odontogenic Tumor

Journal of Oral and Maxillofacial Surgery, 2012
The purpose of this study was to answer this clinical question: When a patient presents with a radiolucent lesion of the mandible presumed to be an odontogenic cystic lesion, to what extent is the radiographic finding of multilocularity predictive of a final diagnosis of keratocystic odontogenic tumor (KCOT)?The study sample was derived from the ...

[Keratocysts (or keratocystic epithelial odontogenic tumors)].

Revue de stomatologie et de chirurgie maxillo-faciale, 2011
The aim of this study was to describe the management of keratocysts based on our own experience and on a large literature review. Keratocysts are benign odontogenic epithelial tumors. The main aspects of this lesion are described (definition, epidemiology, clinic, radiology, histology, treatment, and prognosis).
