Calcifying cystic odontogenic tumor accompanied by a dentigerous cyst: A case report

Abstract

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third decades of life. The present study reports an asymptomatic case in a 13-year-old boy who was referred to the outpatient clinic of the Osaka Dental University Hospital (Osaka, Japan) for additional investigation of an area of radiolucency in the lower right jaw. X-ray demonstrated a unilocular, well-circumscribed, radiolucent lesion in the mandible, which measured 30×20 mm, with radiopaque structures within it. Enucleation of the lesion with tooth extraction was performed, which histopathologically revealed features of a CCOT and a cyst. To the best of our knowledge, the occurrence of such a lesion has not been previously identified. The present study examined the significance of the case with a brief review of the literature.

Calcifying odontogenic cyst associated with an antral pseudocyst: treatment of an uncommon case report and update of main findings

“…In addition, impacted or dislocated adjacent teeth are also frequent. 23 In another study, three COCs were associated with odontomas and one with ameloblastomas. 24 The present case report suggests an association between a COC and an AP, which has not been mentioned in the literature.…”

Calcifying odontogenic cyst: A case report

“…It is this unique feature that also differentiates it from an ameloblastoma. However, the synchronous occurrence of COC with ameloblastomas and other odontogenic pathologies including dentigerous cysts, ameloblastic fibromas and odontomas has been reported. COCs are complex lesions and can have substantial variation in the morphology of the epithelium, with several different lesions incorporated, including other odontogenic cysts and/or tumours.…”

Clinical and Radiological Approaches of Calcifying Odontogenic Cyst of Maxilla – A Case Report

“…The subdivisions of Cystic type include simple cystic type, odontoma producing type and ameloblastomous proliferating type, whereas the neoplastic type compromises solid lesion such as Dentinogenic Ghost cell tumor [8]. Radiographically in early stages the lesion will appear completely radiolucent, as it matures calcifications form that yields a mixed radiopaque and radiolucent lesion [9]. The presence of calcifications is a very unique finding in COC.…”
