Abstract
Calcifying odontogenic cyst (COC) is a rare, developmental odontogenic cyst that usually arises in the anterior region of the jaws. An 18-year-old, dark-skinned man was referred for evaluation of a painless, slow-growing swelling in the maxilla, extending from tooth #21 to tooth #25. Extraoral examination revealed slight elevation of the left nasal ala, producing discrete facial asymmetry. Computed tomography showed an expansive, unilocular hypodense lesion with small hyperdense foci, measuring approximately 3.0 cm in diameter. Under the diagnostic hypothesis of COC, an incisional biopsy was performed. Histopathological analysis disclosed a cystic cavity lined by ameloblastoma-like epithelium, with focal accumulation of ghost cells. Calcifications within the ghost cells could also be observed. The definitive diagnosis was COC. The patient was referred for surgical treatment and remains under close follow-up.
