The calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign tumor of epithelial origin of locally aggressive behavior, which represents less than 1% of all odontogenic tumors affecting the oral cavity. The lesion usually presents as a nonulcerated painless mass of slow growth, commonly affecting the posterior region of the mandible. Depending on the stages of development, CEOTs may present variable radiographic appearances. To date, a few number of cases affecting the anterior maxillary region have been published in the English-language literature. This article describes an interesting and rare case of an anterior ulcerated maxillary swelling diagnosed as a CEOT based on clinical, cone beam computed tomography and pathologic findings. Functional results were obtained with the surgical approach, and no recurrence of the lesion during a 2-year follow-up period was observed.
