Abstract
Introduction: Odontogenic keratocyst (OKC) is an odontogenic lesion with aggressive biological behavior, which occurs mainly in the posterior region of the mandible. Late diagnosis and treatment of this lesion is a significant diagnostic challenge.
Case report: The patient was a 12-year-old boy with complaints of progressive and painful swelling in the mandible for the past two months. The lesion ranged from the right first molar to the left first molar of the mandible. Panoramic radiography revealed a large multilocular radiolucent lesion with well-defined borders, which had caused bone loss and displacement of adjacent teeth. Considering the extension of the lesion in the midline region, the young age of the child along with other clinical and radiologic findings, the diagnosis of OKC was suggested which was ultimately confirmed by histopathologic examination.
Conclusion: The extensive spread of the lesion in an unusual site of OKC occurrence, its growth pattern, and the simultaneity of its occurrence with vitiligo in this case highlight the importance of reporting this case.
