Calcifying odontogenic cyst causing an atypical complication: Case report


 Introduction: Calcifying odontogenic cyst (COC) is a benign cystic type of odontogenic tumor, without neoplastic character and unusual in nature. Its development is slow and asymptomatic, being characterized by a mass that affects the maxilla and mandible.

 Case Report: A 40-year-old male presented with mild extra and intraoral facial swelling in the region of the right upper incisors, without symptoms. On intraoral examination, he observed intact and normal colored buccal mucosa. Radiographic examination showed a radiolucent lesion between teeth 11 and 12. Excisional biopsy was performed. The histological diagnosis was calcifying odontogenic cyst.

 Conclusion: Calcifying cyst is an uncommon odontogenic cyst that most often occurs in the maxilla. However, it should be in the differential diagnosis of other odontogenic lesions. In addition, after conservative surgical removal, long-term follow-up is recommended. Because, although rare, recurrence can occur.
