Calcifying Odontogenic Cyst Associated with Impacted Mandibular Canine: A Case Report

The calcifying odontogenic cyst (COC) is a rare cystic lesion, mainly affecting the anterior aspect of the jaws. It is usually discovered in unexpected settings and can be clinically observed as a painless and well-defined lesion. The COC may be associated with other odontogenic tumors, such as odontomas. Nearly 50% of COCs are associated with an unerupted tooth, most often a canine. The most unique features of this pathology are histopathological features, including a cystic lining with characteristic ghost epithelial cells with a tendency for calcification. Radiological examinations often reveal a radiolucent and unilocular lesion, sometimes associated with radiopaque lesions. Pathological assessments are required for the final diagnosis. Management is through complete excision with annual radiographic monitoring for five years.

Here, we report a classic case of COC in the left mandibular region associated with an extremely displaced impacted canine in a 16-year-old girl.

Although uncommon, COCs are frequently associated with impacted teeth. The radiolucencies associated with impacted teeth have different effects on the surrounding structures and require different treatment plans, depending on the type of the lesion.
