In this study, we compared mast cell tryptase and CD31 expression between odontogenic tumors with the aim of predicting the clinical behavior of these lesions at the time of initial biopsy. We also evaluated the correlation between mast cell tryptase and CD31 expression to clarify the role of mast cells (MCs) in the growth of odontogenic tumors. Immunohistochemical staining with anti-MC tryptas...

Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor which is characterized by the presence of islands and sheets of epithelial cells, amyloid like material and calcifications. These calcifications have a concentric lamellar pattern because of which they have been known by some as liesegang rings. However, classic liesegang rings seen in other extragnathic sit...

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign lesion. A case of CEOT in the left mandible of a 46-year-old man is presented. This case is exceptionally unusual because it was left untreated for 10 years, indicating in some way the course of the tumor. Histologic findings both at the time of first diagnosis and at the final treatment 9 years later were identical.

The calcified epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign but locally aggressive lesion. Usually this tumor is located in the molar premolar region of the lower jaw. There is no sex predilection and the lesion most frequently occurs during the fourth and fifth decade of life.

Calcifying Epithelial Odontogenic Tumor (CEOT) is a rare benign odontogenic tumor that was first described by Pindborg in 1955. It accounts for less than 1% of all odontogenic neoplasms. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. The radiographic appearance is characterized by unior multilocular radiolucent areas with radiopaque masses of var...
