Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately one percent of all odontogenic tumors. Extra osseous variant is very rare with very few cases being reported in literature Peripheral Calcifying epithelial odontogenic tumor (CEOT) commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous coun...

SUMMARY Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma.

OBJECTIVES Odontogenic tumours comprise a large heterogeneous group of lesions originating from odontogenic epithelium and/or ectomesenchyme and its vestiges. The aim of this study was to analyze odontogenic tumours in children and adolescents seen at a tertiary institution in South Western Nigeria and compare with results from previous studies. MATERIAL AND METHODS Archival records of the De...

calcifying epithelial odontogenic tumor (ceot) is a rare benign, but locally infiltrating odontogenic neoplasm. it accounts for less than 1% of all odontogenic tumors. this is a case report of recurrent ceot in the maxilla. a 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. it is of particular concern because of its anatomic location in the m...

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...

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...

Background: The calcifying odontogenic cyst (COC) is a rare example of a developmental odontogenic cyst. COC may clinically be diagnosed as calcifying epithelial odontogenic tumour, adenomatoid odontogenic tumour, ameloblastic fibroodontoma, complex or compound odontoma, dentigerous cyst or as other types of odontogenic cysts. Purpose: The aim is to present an unusual clinical case of COC assoc...

A 36-year-old woman was examined and treated for a rare odontogenic tumor in the mandible, the calcifying epithelial odontogenic tumor (CEOT), also known as the Pindborg tumor. The tumor extended from the left mandibular molar region to the right premolar area and had almost completely destroyed the bone in the anterior mandibular region. An orthopantomogram showed a multiloculated radiolucent ...
