Recurrent calcifying epithelial odontogenic tumor (Pindborg tumor): A case study

Abstract

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign but locally aggressive odontogenic neoplasm first described as an entity by a Dutch pathologist Jens Jorgen Pindborg in 1955. It accounts for less than 1% of all odontogenic lesions. In 1976, a review of the world literature comprising 113 cases was published. Presently, there is still no documented case of a Filipino with this type of odontogenic tumor. Although Pindborg tumors have characteristic clinical and histopathologic features some variants can mimic malignant neoplasms. We report of a case of recurrent calcifying epithelial odontogenic tumor which showed cytologic features of malignancy. Definitive resection of the entire mass with tumor-free surgical margins and long-term follow up are recommended.
