Calcifying odontogenic cyst of anterior maxillary: Case report and review

Abstract

Introduction and importance Calcifying odontogenic cyst (COC) is a rare lesion of jawbone. It is classified among development cyst in the new WHO classification of tumors of the head and neck in 2017. It is a rare pathology, which is found more in the upper maxillae, with a predominance in women in the second or third decade. The diagnosis is based on the analysis of clinical, radiological and histological features. Case presentation We report the case of a 17-year-old patient referred by his orthodontist following the fortuitous discovery of a mixed radiolucent/radiopaque image in the right jaw ranging from the tooth 11 to the tooth 16, for whom the clinical, radiological examination associated with fine needle aspiration cytology suggested a cystic lesion. Clinical discussion Management initially consisted of decompression of the lesion and complete enucleation after nine months. Histopathological examination gave the diagnosis of calcifying odontogenic cyst. The follow-up showed favorable evolution.

Calcifying odontogenic cyst associated with compound odontoma – A rare entity

“…According to the study by Uchiyama and al COC are unilocular with well-defined borders and margins, root resorption was encountered in seven of nine cases with divergence of teeth in eight of the nine cases, impacted teeth were reported in six of the nine cases, an odontoma was found in one case. [ 5 ] Hirshberg et al [ 21 ] clinically and histologically examined 52 cases of Gorlin cyst, associated with odontoma. [ 13 ] Lida et al [ 22 ] reported radiographic profile of 11 cases of COC and only one of them arose from edentulous mandible.…”

“…In 1963, Gold introduced the term keratinizing and calcifying odontogenic cyst. [ 4 ] In 1971, COC was included by WHO in its classification of “Histological typing of odontogenic tumors, jaw cysts, and allied lesions.”[ 5 ] It was further classified in 1992 and 2005 by WHO in odontogenic tumors. In latest classification in 2017, COC was classified among the developmental cysts.…”

“…In latest classification in 2017, COC was classified among the developmental cysts. [ 5 ] In addition, the cystic type of COC may be associated with other odontogenic tumors such as Odontoma, Adenomatoid Odontogenic Tumor, Ameloblastoma, Ameloblastic Fibro-Odontoma and Ameloblastic Fibroma COC may also be associated with impacted teeth. [ 3 ] Clinically, it is characterized by slow growing painless swelling.…”

Multidisciplinary Case Management in Mesiodens Impacted Cases with Calcifying Odontogenic Cyst

“…Considering the complexity of the case, we decided to manage the mesiodens impacted case with COC multidisciplinary [ 5 ]. Radiographically, COCs are well-circumscribed and present as a unilocular radiolucency with calcifications of varying density reported in one-third of cases [ 17 ].…”

“…This procedure is aimed at limiting the risk of recurrence. Decompression and marsupialization are conservative treatments used in large lesions with a high success rate [ 5 ].…”
