Atypical radiological presentations of a calcified epithelial odontogenic tumour in the maxilla: A rare case composed of massive calcification

Calcified epithelial odontogenic tumours (CEOTs) are rare benign tumours that tend to arise in the mandible. Calcifications of amyloid-like substances produced by these tumours present as irregular radiopacities on the radiographs. Herein, we report a rare case of a CEOT in the maxillary premolar, which was largely composed of massive calcification and the presence of an impacted tooth. The patient was a 37-year-old male with a chief complaint of tooth mobility and pain in the left maxillary molar. Panoramic X-rays and computed tomography imaging showed an irregular radiopaque lesion with tooth-like structures in the left maxillary premolar. An excisional biopsy was performed after a clinical diagnosis of a benign tumour was suspected. The lesion was histopathologically diagnosed as a CEOT. The postoperative course was good, and the patient is currently under observation.
