What is the Calcifying Odontogenic Epithelial Tumor or Pindborg Tumor?
Calcifying Odontogenic Epithelium Tumors are rare neoplasms that arise from the odontogenic epithelium, and are characterized by the presence of epithelium strung like layers. Pindborg tumors have a percentage of about 1% of odontogenic tumors as a whole.
Reducing Epithelial Odontogenic tumors are usually also called Pindborg tumors. These lesions are very rare for all types of odontogenic tumors.
Clinical features
These tumors are found in patients around the age of 30 and 50 years, not by sex, about 2/3 are found posteriorly, not sick, swelling that is not painful and slow growth is a frequent symptom.
Image Radiology
Tumors appear unilocular but are more often multilocular radiolucents. The edges that occur due to lysis are often squiggly. The lesion may be radiolucent inside, but it is possible that the structure is calcified with varying shapes and densities. These lesions are usually published with impacted teeth especially third molars. Areas that calcify usually around the crown of the teeth.

Histopathological features
These tumors have a precise picture, visible polyhedral epithelial cells in the fibrous stroma. The nucleus for various variations and usually looks giant nucleus. The amarphous, eosinophylic, extracellular material is hallucinated and often visible. These tumors are often covered in mass from these hyalin ingredients. Calcification found in tumors develops in materials such as amyloids and concentric rings (Liesegang ring calcification).

Management and Prognosis
Conservative local resection in certain areas around the visible bone. The record that has been done is approximately 15%. Tumors used with curettage that form a higher level of recurrence.
