Background: The odontogenic keratocyst, usually located in the posterior mandible, exhibits a unilocular or multilocular radiolucent area and well-defined histopathological characteristics.
Case Presentation: A 41-year-old woman with an asymptomatic swelling in the anterior maxilla that progressed over two months. Radiographic examination using a panoramic radiograph revealed a mixed image with radiopaque foci. Differential diagnoses included desmoplastic ameloblastoma and ossifying fibroma. A histological analysis revealed an epithelium lining a capsule characterized by a basal layer of columnar palisaded cells and a wrinkled parakeratin layer. In some areas, the epithelium was detached from the capsule, and many areas of dystrophic calcification were observed in the capsule.
Conclusion: Although some studies mention calcifications in the capsule of the keratocyst, there is no conclusive study on the mechanism of development of these calcifications. This keratocyst is notable because exhibits extensive areas of calcification that, to the best of our knowledge, have not previously been reported.
