Abstract
The odontogenic keratocyst (OKC) is a developmental cyst originated from the cell debris of the dental lamina. This lesion affects the mandible in 60% to 80% of cases, and the posterior body and mandible ramus are the most frequently affected regions. The following clinical case report is about a 24-year-old male patient without comorbidities who complained of facial swelling. On the panoramic radiographic exam, the presence of unilocular circumscribed radiolucent image was observed in the body and in the right mandible ramus, suggesting the hypothesis of OKC. The patient underwent surgical enucleation under general anesthesia for total removal of the lesion. The collected soft tissue fragments were sent for anatomopathologic analysis, in which microscopy revealed a cystic fibrous wall coated with parakeratinized stratified squamous epithelium showing atrophy without atypia that confirmed the diagnosis of OKC. After 8 months of postoperative follow-up, satisfactory healing and considerable bone repair at the lesion site could be observed.
