Calcifying epithelial odontogenic tumor (CEOT), also known as a Pindborg tumor, (previously has been called adenoid adamintoblastoma, unusual ameloblastoma and cystic odontoma) is typically located in the premolar and molar region of the mandible, although up to a third are found in the maxilla.
Usually they are seen in the 4th to 6th decades. They are rare tumors.
Half are associated with an unerupted/impacted tooth.
They are usually radiolucent with scattered areas of calcification, although this can vary from completely radiolucent (seen early on) to more uniformly dense. If present, radiodensities tend to be clustered around a tooth.
The margins a variable in appearance, either well defined or indistinct. They can be uni- or multiloculated.
History and etymology
The first case was described in the literature in 1955 by Jens Jørgen Pindborg, Danish oral pathologist (1921-1995) 2.
