Calcifying Epithelial Odontogenic Tumour (Pindborg Tumour): Report of Two Clinical Cases with A Rare Maxillary Localization

Abstract

A calcifying epithelial odontogenic tumour (CEOT) or Pindborg tumour is a rare benign eithelial odontogenic neoplasm that was first described by Jens Jorgen Pindborg in 1955. It accounts for less than 1% of all odontogenic tumors [1]. This benign odontogenic tumour is slow growing and expansile. The age of discovery varies between the third and fifth decades, and the M/F sex ratio is balanced. Involvement of the mandibular molar region is more frequent.Clinically, the tumor may evolve silently, and discovery is often fortuitous or the result of swollen tooth movements.Radiologically, it may be homogeneous or heterogeneous, with or without calcifications. The origin of the tumor remains debated, and treatment is surgical, involving simple enucleation.The aim of this work is to report two cases of Pindborg tumor with a rare maxillary localisation and to discuss its clinical and radiological signs.
