12 Year Pediatric Patient Having Pindborg Tumour an Intraosseous Variant: A Rare Case Presentation Affecting the Maxilla

Pindborg tumor is a rare benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. I herein report a case of a 12 year old pediatric male patient with a painless swelling of the left maxilla of 5 months duration. Radio graphically, a well circumscribed unilocular radiolucency containing radiopaque foci associated with impacted tooth was seen, along with cortical bone expansion. Histopathology showed sheets of polyhedral epithelial cells in a fibrous stroma. Cells showed distinct cellular outlines with prominent intercellular bridges. Large areas of amorphous, eosinophilic, hyalinized material seen and calcifications within the amyloid-like material (Liesegang ring calcifications) were evident, confirming a diagnosis of Pindborg tumour (Calcifying Epithelial Odontogenic Tumor). The patient was treated by surgical excision of the tumor.
