odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

Abstract Introduction: Pigmented odontogenic lesions are rare; to date, only 60 cases have been reported in the literature. Melanocytes have been detected in a wide variety of odontogenic lesions. Several studies have discussed melanocyte presence and melanin production in odontogenic lesions, but its origin is still unclear. Therefore, the present systematic review aimed to gather information...

BACKGROUND The purpose of the study was to correlate the provisional diagnosis of pericoronal radiolucencies associated with impacted, embedded, or unerupted teeth with the histopathologic diagnosis, and also to emphasize the importance of early detection for better diagnosis and management. METHODS This is a retrospective study involving 18 cases of pericoronal radiolucencies associated with...

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...

Glandular odontogenic cyst (GOC) is considered an odontogenic cyst of developmental origin, which because of its histological features had been termed sialo-odontogenic cyst. Although clinically and radiologically they bear similarity to relatively innocuous periapical lesions, their biological behavior is comparable to aggressive tumor-like conditions-like keratocystic odontogenic tumors. Thei...

P63 may have a role in tumorigenesis and cytodifferentiation of odontogenic lesions. We investigated the immunohistochemical expression of P63 in a total of 30 cases of odontogenic cysts and tumors. The percentage of positive cells was calculated in the lining of odontogenic cysts and islands of ameloblastoma. P63 expression was evident in all types of odontogenic lesions. P63 was expressed thr...
