Radiologic-Pathologic correlation of Pindborg tumor of maxilla with extension to maxillary sinus, nasal cavity, and infraorbital margin: A case report.

Calcifying epithelial odontogenic tumor is a benign epithelial odontogenic tumor thought to originate from the stratum intermedium. Clear cell type, Langerhans cell/non-calcified type, and cystic/microcystic are the three recently recognized histological subtypes of CEOT in the 5th edition of the World Health Organization Classification of Head and Neck Tumors. Almost 350-400 cases of CEOT have been reported in literature, accounting for less than 1% of the reported cases of odontogenic tumors. We are reporting a case of Pindborg tumor of the maxilla with extension to the maxillary sinus, nasal cavity, and infraorbital margin, with an emphasis on radiographic and histopathologic presentation.
