Clear Cell Variant Of Pindborg’s Tumor In Anterior Mandible: Case Study And Overview Of Other Histological Variants.

Pindborg tumour or calcifying epithelial odontogenic tumor (CEOT) is a rare and benign odontogenic neoplasm that was first described by a Dutch pathologist Jens Jorgen Pindborg in 1955. The most common clinical manifestation of CEOT is that of a localized, slow growing hard tissue swelling of the posterior jaws. Radiographically, it presents as a mixed radiolucentradiopaque lesion. Though the histopathological presentation is quite distinct, cases have been reported to show slight variations from the usual picture. One such rare variant is the presence of abundant clear cells intermixed with the tumor cells. The significance of this variant is that it has been shown to have a more aggressive behaviour with greater tendency to recur if inadequately removed. We report a case of clear cell variant of CEOT with an uncommon site of presentation in the anterior mandible.
