Pindborg tumor: Review of literature and case reports

Abstract

Pindborg or calcifying epithelial odontogenic tumor (CEOT) is a benign and noninvasive tumor that presents poor clinical features, a typical radiological picture and a characteristic histomorphology. CEOT is an uncommon odontogenic neoplasm, representing only 1% of all odontogenic tumors. The average age of occurrence is around 40 years with almost 1:1 gender ratio. It shows a mandible: maxilla site ratio of 2:1 and is mainly located in the molar: premolar (3:1) region. The tumor usually appears as a radiolucent area containing radiopaque masses scattered throughout. Histologically, it is characterized by densely eosinophilic cells, which tend to calcify, homogeneous eosinophilic substance believed to be amyloid and calcifications in concentric layers (Liesegang rings). Two case reports are presented here in patients aged 30 years and 14 years.
