Resumo (EN)
The calcifying cystic odontogenic tumor (CCOT) is a rare odontogenic lesion derived from the remaining odontogenic epithelium of the maxilla or mandible. Its occurrence in the maxilla and mandible is similar, however, the canine region is the most affected when compared with other regions. The aim of this paper is to relate the case of a patient who presented a CCOT in the left region of the maxilla, between the canine and the first premolar, characterized by an increase in volume that was painful on palpation. The lesion presented a well circumscribed radiolucent radiographic image, however, presented no root resorption and radiopacities suggestive of dystrophic calcification, common signs in this tumor. With the diagnostic hypothesis of a lateral periodontal cyst, enucleation of the lesion was performed. The patient has been followed-up for around 15 months without signs of recurrence.
