Abstract
Odontogenic keratocyst (OK) is a controversial lesion classified by the WHO in 2005 as an odontogenic tumor and, more recently, in 2017, it was again classified as a developmental odontogenic cyst. It is characterized by local invasiveness and high recurrence rates. It presents, in most cases, asymptomatic and has a higher incidence in the mandible. The aim of this article is to report a clinical case of OK in the maxilla describing its characteristics and treatment. A 15-year-old male patient sought the Maxillofacial Surgery service at Hospital do Oeste, Barreiras/ BA, complaining of swelling in the maxillary region, with a diagnostic hypothesis of cyst based in routine panoramic radiography. For better diagnostic elucidation, a multi-slice computed tomography was performed, where a hypodense, multilocular image was observed in the right maxilla, which histopathologically confirmed to be a OK. Surgical treatment with curettage and patient follow-up was performed. OK is one of the most frequent odontogenic lesions in the jaws, that’s why it is very important to know the clinical, radiographic, and histopathological characteristics, in addition to professional experience for the diagnosis and treatment of this pathology.
