Calcifying epithelial odontogenic tumour

Dr Frank Gaillard et al.

A calcifying epithelial odontogenic tumour, also known as a Pindborg tumour 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 4^thto 6^th decades. They are rare tumours (see mandibular lesions)

Associations

Half are associated with an unerrupted / impacted tooth.

Radiographic features

They are usually radiolucent with scattered areas of calcification, although this can vary from completely radiolucent (seen early on) to more uniformly dense : although radiodensities tend to be clustered around a tooth (if present).

The margins a variable in appearance, either well defined or indistinct. They can be uni or multiloculated, and are difficult to distinguish from an ameloblastoma.
