Pindborg tumor arising in association with an impacted supernumerary tooth in the anterior maxilla.

Pindborg tumor/Calcifying Epithelial Odontogenic Tumor (CEOT) is a benign epithelial odontogenic tumor which shows locally aggressive behavior and accounts for less than 1% of all odontogenic tumors. The most frequent location is the mandibular premolar and molar area; less frequently the lesion is found in the maxilla. Since histopathology remains the main method for definitive diagnosis, this lesion presents an enigma to a clinician when lesions occur in atypical locations. The authors report a case of CEOT in the maxillary anterior region associated with an impacted supernumerary tooth (mesiodens).
