Calcifying epithelial odontogenic tumor (Pindborg tumor), is a rare benign odontogenic neoplasm representing about 0.4-3% of all odontogenic tumors. This tumor more frequently affects adults in the age range of 20-60 years, with a peak incidence in the 5th decade of life. Calcifying epithelial odontogenic tumour has a much lower recurrence rate than ameloblastoma and malignant transformation, a...

The expression of genes of biogeochemical interest in calcifying and noncalcifying life stages of the coccolithophore Emiliania huxleyi was investigated. Transcripts potentially involved in calcification were tested through a light-dark cycle. These transcripts were more abundant in calcifying cells and were upregulated in the light. Their application as potential candidates for in situ biogeoc...

Discussion The name tricho-epithelioma indicates that in this tumour differential diagnosis is directed towards the hair structures. Reese (1951) states that these tumoursmay be single or multiple, are noticed in early life, and grow very slowly, and that there may be some keratinization as in our first case. In our three cases the tumours appeared for the first time when the patients were aged...

Sustained release of 1,3-bis(2)chloroethyl)-1-nitrosourea (BCNU) via an episcleral implanted silicone device was used to treat Brown-Pearce epithelioma in the anterior chamber of rabbit eyes. One group of test eyes received BCNU dissolved in sesame oil; a second group received BCNU in pure ethanol. Control eyes received only the diluent, sesame oil or pure ethanol. The effectiveness of the vari...

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...

Background & Aims: Calcifying nanoparticles are different forms of calcium and phosphate in sediments. Recent evidence suggests that calcifying nanoparticles (CNPs) are probably selfreplicating. Several diseases are linked to nano-bacteria including kidney stones, gallbladder stone, cardiovascular plaques, oral–dental plaque, many cancers, and autoimmune diseases. The aim of this study was to a...

We herein report a rare case of extraosseous calcifying epithelial odontogenic tumor with local aggressive behavior. CT and MR imaging showed the distinctive appearances of this histologic entity. We briefly discuss the radiologic features of calcifying epithelial odontogenic tumor and the relevant literature.
