Calcifying odontogenic cyst: A case report

Abstract

A calcifying odontogenic cyst (COC) is a rare odontogenic lesion with a vast variety of clinical, radiological, histopathological features and biological behaviours. In this article, we illustrate a case of an 18‐year‐old male patient with a complaint of an 18‐month history of swelling in his right maxilla. The lesion was diagnosed as a COC associated with an impacted 18 using radiological, cytological and histopathological investigations. The present study examines and considers the case.

Calcifying epithelial odontogenic cyst of maxilla: Report of a case and review and discussion on the terminology and classification

“…Recurrences, though uncommon, are frequently seen, especially in relation to neoplastic cases such as dentinogenic ghost cell tumors. [ 7 29 30 ]…”

Calcifying Odontogenic Cyst of the Oral Cavity: A Clinical Case and Current Updates on the Ethiopathogenesis

“…COC is thought to arise from the reduced enamel epithelium surrounding the unerupted crown or from the remnants of the dental lamina. It is a cystic lesion which his-tologically shows an odontogenic and ameloblastomatous epithelium lining along with ghost cells and focal calcifications and with nests of an eosinophilic material in the capsule, defined dentinoid [1] [2] [3] [4]. Melanin deposits could be found between epithelium cells [5] [6].…”

“…The male sex adult seems to be the most frequently affected in the anterior maxilla. From a therapeutic point of view, intraosseous COC is mainly treated by enucleation, with a low rate of recurrence, occurring in <5% of cases, while extra-osseous lesion is treated with excision [1] [4] [9]. There are reports of malignant transformation in recurrent cases of COCs, thus, long-term follow-up of such patients should be performed [5] [9].…”

“…In the current WHO classification and also in other proposed classifications on odontogenic cysts, COC is included among the odontogenic cysts "developmental/with tumoral variants" and COC and CCOT are considered synonyms [3] [4]. In fact, some COCs show more aggressive behavior than others and this determines a different consideration in the surgical approach [5] based on the dualistic etiological concept of two biological entities of similar origin but with different biological behavior [1]…”

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

“…It most commonly involves the incisor canine areas and rarely involves posterior maxilla [2].The World Health organisation in 2005 described COC as a benign cystic tumor which arises from the odontogenic epithelium with or without hard tissue formation, but later in 2017 they reclassified COC under developmental odontogenic cysts [3].The characteristic feature of COC is the presence of Ghost cells within the epithelium that tend to calcify [ 4].these lesions occur most commonly in the second decade of life with equal susceptibility to both the genders. It can be either intraosseous (central) or extraosseous (peripheral) [5].…”
