Abstract: Background and Aim: Compare with Dentigerous cyst, Odontogenic Keratocyst is one of exclusive developmental cyst with unique clinical and histopathologic features. Considering the determining role of epidermal growth factor receptor (EGFR) in cell proliferation and survival, and the controversial results of previous studies regarding the expression of this marker by the odontogenic cy...
Keratocystic odontogenic tumors (KCOTs) are certainly among the most studied lesions in oral pathology, which is not a surprise considering their perplexing clinical behavior and complicated mechanism of pathogenesis. In fact, the specific KCOT features are the reason for numerous discussions regarding the true nature and classification of these lesions, which are still debated in the scientifi...
OBJECTIVES Botryoid odontogenic cyst (BOC) is considered as an unusual multilocular variant of lateral periodontal cyst (LPC). Review of the literature indicates that this lesion has higher risk of recurrence than LPC, but objective reasons are still unknown. The aim of this study is identify main clinical and pathological variables associated with the risk of recurrence. STUDY DESIGN A compl...
Correspondence to: Luís Monteiro Rua António Moreira da Silva, 175 4475-457 Maia Portugal E-mail: [email protected] Abstract Odontogenic cysts are lesions that deserve every attention, mainly because of all complications they can cause. To study their characteristics, the authors did a retrospective clinicopathological analysis of 124 oral biopsies that were diagnosed as odontogenic cyst...
Antral pseudocyst (AP) is a process formed by the inflammatory exudate accumulation below the sinuses mucous membrane and causing a sessile elevation. AP is a dome-shaped, well-delineate, faintly radiopaque lesion on the intact floor of the maxillary sinus. A case of AP with an unusual location is presented. A 24-year-old male was submitted to the panoramic radiographic exam and an around, well...
the lateral periodontal cyst is an uncommon, but well-recognized type of developmental odontogenic cyst. lateral periodontal cysts are defined as non-keratinized and non-inflammatory developmental cysts located adjacent or lateral to the root of a vital tooth. it is a relatively uncommon lesion found mostly in adults (5th to 7th decades) and it is rare in young people under 30 years of age. a c...
BACKGROUND Odontogenic cysts are those which arise from the epithelium associated with the development of teeth. Some odontogenic cysts were found to have special biological features that make them distinct from other lesions. This study was conducted to detect the immunoepxression of laminin-1 and Ki-67 in both radicular cysts (RCs) and keratocystic odontogenic tumors (KCOTs) and to examine th...
The pattern of distribution and expression of laminin and type IV collagen was studied in ten radicular cysts, ten dentigerous cysts and ten odontogenic keratocysts, by means of the streptavidin-biotin method. The purpose of this study was to investigate changes in the distribution of components of the basement membrane in an attempt to contribute to the understanding of the differences, as to ...
Background & Aim: Jaw cysts are uncommon lesions that frequently behave aggressively and attain a large size. For definite diagnosis clinicoradiopathologic features are needed. Due to a great similarity between historical, clinical and radiological features of jaw cysts, the differentiation of one from another just by regarding one of these data is impossible. Not enough information is avai...
Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differ...
