Calcifying odontogenic cyst: Radiologic findings in 11 cases

A Calcifying Odontogenic Cyst With Compound Odontoma in the Maxillary Sinus: A Case Report in a Pediatric Patient

Calcifying odontogenic cysts (COCs) exhibit a diverse clinical course, commonly developing between the second and third decades of life, displaying no gender predilection. A 15-year-old female without medical history was under observation for a mixed lesion in the maxilla associated with an impacted tooth. She presented to the emergency department with sudden onset and worsening swelling of the left midface. Radiographic findings in the panoramic radiograph and a CT scan revealed a well-circumscribed mixed lesion localized in the left maxilla, extending into the left maxillary sinus and reaching the orbital floor. After an intercurrent infection of the cyst, the patient was hospitalized, received intravenous antibiotics, and went for surgical intervention under general anesthesia. Lesions that combine histological characteristics of two or more odontogenic tumors or individual cysts in the same location are called hybrid odontogenic lesions. This type of lesion poses a challenge for both pathologists and surgeons, because of its controversial histogenesis and poorly understood clinical evolution. The most common of these lesions are COCs associated with odontoma. Our case represents an exceptionally rare entity among odontogenic cysts.

Compound odontoma associated with a calcifying odontogenic cyst. Case report and systematic review

The objectives of the present study were to comprehensively evaluate all the published cases on compound odontoma associated with calcifying odontogenic cyst (COaCOC) in the English literature and to describe the clinical, imaging and therapeutic variables for this condition. In August 2020, an electronic search of the PubMed / MEDLINE, Web of Science, ScienceDirect, Springer, and Scopus databases was carried out. The eligibility criteria included publications with enough information to confirm the diagnosis. Furthermore, we present a clinical case of a 16-year-old male patient with OCCaC, who was treated with enucleation, obtaining favorable and functional results. A total of 32 cases reported in the literature that met the inclusion and exclusion criteria, including ours, were analyzed and discussed. The mayority of the patients were women (n = 17) with an average age of 14.4 years, the maxilla was the most affected bone (n = 22) and the maxillary anterior region was the area with the highest number of cases (n = 18), the main clinical presentations were the volume increase (n = 14) and asymptomatic (n = 14). The choice treatment was enucleation (n = 26) and, in most cases, no recurrence was reported (n = 20). This study allows to update the characteristics of the OCCaC, giving an effective vision of how to treat this rare pathological association made up of two conditions that are completely different from each other.

Primary intraosseous carcinoma in the pediatric and adolescent mandible

BACKGROUND

Primary intraosseous carcinoma (PIOC) is a rare malignant odontogenic tumor that predominantly occurs in males older than 50 years. PIOC can be misdiagnosed as odontogenic cyst because it occasionally shows a well-defined border on radiography. In this study, related literatures of pediatric and adolescent PIOC cases were analyzed under strict PRISMA guidelines along with an adolescent case who was provisionally misdiagnosed as an odontogenic cyst.

METHODS

All case reports for PIOC published in English from 1966 to 2021 were collected. Cases under the age of 20 were classified as pediatric and adolescent populations in this study. A total of 12 pediatric and adolescent cases including 11 PIOCs from the literature and one new case of a 14-year-old female were analyzed. Clinical and radiographic features, diagnosis and treatment approaches, and prognosis were investigated.

RESULTS

Ages ranged from 4 to 18 years. The female to male ratio was 1.4:1. Seven cases occurred in the mandible. Swelling was observed in 11 patients. The radiologic borders were well-defined in six cases and corticated in four cases. Tooth displacement and root resorption were observed in four and six cases, respectively. The provisional diagnosis for seven patients was odontogenic cyst and enucleation was performed in six cases including the new case. During the follow-up period, local recurrence occurred in three patients. The pediatric and adolescent PIOC cases with local recurrence showed poor prognosis. The locally recurred lesion in the new case did not decrease in size despite concurrent chemo-radiation therapy.

CONCLUSIONS

Three-dimensional imaging modalities and incisional biopsy with multiple specimens are necessary to rule out PIOC in the lesions with atypical radiographic findings. PIOC should be diagnosed differentially from odontogenic cyst even in pediatric and adolescent populations to properly manage the disease with poor prognosis.

Calcifying odontogenic cyst of anterior maxillary: Case report and review

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.

A Calcifying Odontogenic Cyst Associated with Compound Odontoma Mimicking a Tooth Germ

Calcifying odontogenic cyst (COC) is a rare cyst that affects mainly the anterior region of the jaws. Generally, it appears as a unilocular radiolucent lesion containing peripheral foci of calcification, but with radiographic variations depending on the type of presentation. Here, we report an atypical case of COC associated with odontoma, initially diagnosed as a tooth germ, in the posterior region of the mandible of a 10-year-old male patient. Interestingly, the radiographic aspect appeared as a unilocular radiolucent lesion without peripheral foci of calcification in the edentulous region, having its size increased after traction of the impacted tooth adjacent to that area. Thus, the case presented in this study is aimed at calling dentists' attention to its developmental changes and related pathologies.

Differential diagnosis between calcifying odontogenic cyst and adenomatoid odontogenic tumor by computed tomography images

OBJECTIVES

Calcifying odontogenic cysts (COC) and adenomatoid odontogenic tumors (AOT) have similar radiographic findings. We examined the radiographic and computed tomography (CT) images of patients histologically diagnosed with COC or AOT and identified their characteristic findings.

METHODS

The subjects included 12 patients histologically diagnosed with COC or AOT (one female and five males per group), who underwent CT at our hospital between Nov 1998 and Jun 2019. The location of the lesion, impacted tooth, bone expansion, root resorption, tooth migration, calcified body, and presence or absence of a high-intensity zone in the marginal area of the lesion were examined.

RESULTS

In patients with COC, five patients with COC exhibited bone expansion toward the buccal side. The lesion encompassing the crown was attached to the cement-enamel junction and contained a radiopaque lesion with a calcified body. In 6 patients with COC, irregularly shaped calcified bodies were observed with small tooth-like structures. In patients with AOT, all six patients with AOT exhibited bone expansion toward the buccal and lingual sides. The lesion encompasses a part of the tooth root or the entire tooth. Punctate calcification was observed within the lesion and the marginal area in three patients, and a high-intensity zone was observed in the marginal area of the lesion in two patients.

CONCLUSION

We report imaging findings that may be characteristic of COC and AOT, suggesting that CT findings may be useful for differentiating between COC and AOT.

Calcifying odontogenic cysts: A 20-year retrospective clinical and radiological review

OBJECTIVE

Calcifying odontogenic cysts (COCs) exhibit diverse clinical behaviours and may be associated with other benign odontogenic tumours. In this study, the clinical and radiological features of COCs were analysed according to subtypes based on the classification by Praetorius et al. Emphasis was placed on cases exhibiting atypical or aggressive radiological appearances. This information may assist the clinician to better understand the radiological spectrum of COCs.

METHODS

Histologically confirmed cases of COCs were retrospectively reviewed in a 20-year period from three tertiary institutions. The following clinical information was reviewed: patient demographics, main complaint, clinical duration, anatomical site and detailed radiological features.

RESULTS

Twenty-seven cases of COCs were included in the study. Asymptomatic swelling was the main clinical presentation with infrequent reports of associated pain. COCs had an anterior mandibular predilection. Well-demarcated borders were seen in all cases with isolated cases showing focal areas with loss of demarcation. Unilocular lesions were more common than multilocular variants. Internal calcifications were frequent and six cases presented with associated odontomas. Maxillary COCs resulted in the displacement of the maxillary sinus and/or nasal cavity walls. Radiological signs of aggression, including cortical destruction, were noted in a few cases.

CONCLUSION

Given the fact that COCs can present with a spectrum of clinical behaviours and radiological presentations, the academic debate regarding the cystic versus neoplastic nature of the entity is justifiable. The cases in the current sample presented with diverse presentations, ranging from indolent to lesions with significant growth and aggression.

Ghost cell odontogenic carcinoma arising in the background of a calcifying odontogenic cyst

Ghost cell odontogenic carcinoma (GCOC) is a rare malignant neoplasm, representing 3% of all ghost cell lesions of the jaws. They can arise de novo or from a pre-existing calcifying odontogenic cyst (COC) or dentinogenic ghost cell tumour (DGCT). A systematic review of the literature reported only 12 cases of a GCOC arising from a pre-existing COC. This report highlights an additional case of a GCOC arising from a pre-existing COC after 3 years in an adolescent male. The patient initially presented with a painless swelling of the right mandibular corpus. Panoramic radiographic examination showed an expansive unilocular radiolucent lesion. After 3 years, the radiographic features appeared more aggressive with increased expansion and cortical perforation. A wide surgical resection was performed, whereby the lesion was diagnosed as a GCOC. Due to the rarity of these malignant neoplasms, limited information is available regarding their biological behaviour. One-year follow-up revealed no clinical signs of recurrence.

Ameloblastomatous Calcifying Odontogenic Cyst: A Rare Entity

Introduction:

Ameloblastomatous calcifying odontogenic cyst (COC) is an extremely rare histopathologic variant of COC, an odontogenic cyst of the jaws. It needs to be differentiated from closely associated variant ameloblastoma ex COC that is entitled to a more aggressive form of surgical management.

Aim:

The aim of this paper is to present a case of ameloblastomatous COC of the right mandibular angle region with review of literature describing this rare entity. The paper also highlights the requirement of including this lesion in differential diagnosis of various jaw lesions.

Materials and Methods:

Google search, Wikipedia, ScienceDirect, MEDLINE, the Cochrane library, and PubMed were used extensively to search and collect all reported cases of ameloblastomatous COC using keywords such as ameloblastomatous COC, COC, maxilla, mandible, and gorlin cyst ameloblastic proliferation.

Results:

To the best of our knowledge, a total of twenty one cases of ameloblastomatous COC have been reported in the literature in the maxilla-mandibular region and we represent the twenty second case in a 20-year-old female patient along with the review.

Conclusion:

Ameloblastomatous COC – a subtype of COC needs to be differentiated from true ameloblastoma arising from COC as it warrants a conservative form of surgical management unlike other neoplastic variants of COC. Owing to scarcity of data of this lesion in literature, more reporting of such cases is required to shed light on its behavior.

Calcifying Odontogenic Cyst Associated With Dentigerous Cyst in a 15-Year-Old Girl

Calcifying odontogenic cyst (COC) is a rare odontogenic cyst with ameloblastic epithelial lining containing clusters of ghost cells. COCs have been described in association with several odontogenic tumors, more commonly odontomas and rarely with dentigerous cyst (DC). In this article, we describe a case of COC associated with DC in a 15-year-old girl, who presented with a swelling on the right middle third of the face, producing facial asymmetry. Panoramic radiography showed a well-circumscribed, corticated, and unilocular radiolucency at the level of the right maxillary sinus, involving 2 unerupted premolars. The lesion was enucleated and histologically revealed a COC associated with DC, which presented mucous metaplasia. Immunohistochemical reactions were performed to better illustrate this rare synchronous occurrence of COC and DC, showing positivity for CK5, CK14, CK19, and p63 in both lesions. CK18 was negative in COC, and Bcl-2 was negative in DC. Periodic acid Schiff highlighted the mucous cells in the DC lining.

Calcifying odontogenic cyst: A 26-year retrospective clinicopathological analysis and immunohistochemical study

Background

To identify the prevalence and clinicopathological profile of calcifying odontogenic cysts (COC) stored at an oral pathology service, and to analyze the immunoexpression of cyclooxygenase 2 (COX-2) and cyclin D1 (CD1) in these cysts.

Material and Methods

After a retrospective analysis (1990-2016) carried out to identify cases of COC, a sample of 12 cases was selected for immunohistochemical analysis of COX-2 and CD1 by the immunoperoxidase technique. Protein expression was evaluated semiquantitatively by attributing a score of 0 to 3 (0 = no staining; 1 = 1-25%; 2 = 26-50%, and 3 = >51% immunopositive cells).

Results

Twenty cases of COC were diagnosed over the study period. These cysts were more common in the posterior mandible and in men (male-to-female ratio of 1.2:1), with a mean age of 29.9 years. Among the 12 cases analyzed, immunoexpression of COX-2 was observed only in the inflammatory infiltrate in 50% of the cysts (n = 6). Protein CD1 was detected (score 1) in 66.6% of cases (n = 8), and COX-2 was negative in 50% (n = 6).

Conclusions

The prevalence of COC among all odontogenic cysts was 3.5%, representing an uncommon lesion. Immunohistochemical analysis suggested that COX-2 does not participate in lesion progression. The cell proliferation index of COC was low, as demonstrated by the expression of CD1, suggesting a proliferative profile compatible with more indolent lesions.

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

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.

Conservative approach to recurrent calcifying cystic odontogenic tumor occupying the maxillary sinus: a case report

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

Jaw lesions associated with impacted tooth: A radiographic diagnostic guide

This review article aimed to introduce a category of jaw lesions associated with impacted tooth. General search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks were used to find relevant studies using keywords such as "jaw lesion", "jaw disease", "impacted tooth", and "unerupted tooth". More than 250 articles were found, of which approximately 80 were broadly relevant to the topic. We ultimately included 47 articles that were closely related to the topic of interest. When the relevant data were compiled, the following 10 lesions were identified as having a relationship with impacted tooth: dentigerous cysts, calcifying odontogenic cysts, unicystic (mural) ameloblastomas, ameloblastomas, ameloblastic fibromas, adenomatoid odontogenic tumors, keratocystic odontogenic tumors, calcifying epithelial odontogenic tumors, ameloblastic fibro-odontomas, and odontomas. When clinicians encounter a lesion associated with an impacted tooth, they should first consider these entities in the differential diagnosis. This will help dental practitioners make more accurate diagnoses and develop better treatment plans based on patients' radiographs.

Calcifying odontogenic cyst with luminal and mural component (Type 1c)

Calcifying odontogenic cyst (COC) was first described and classified by Gorlin et al. It is defined as a cystic lesion in which the epithelial lining shows a well defined basal layer of columnar cells, an overlying layer that often resemble stellate reticulum and masses of ghost cells that may be in the epithelial cystic lining or in the fibrous capsule. The lesion generally occurs in the region anterior to maxillary and mandibular molars and either intraosseous or extraosseus. This entity might present as a cystic or solid lesion. Praetorius et al. classified COC into 2 main entities namely a cyst (Type 1) and a neoplasm (Type 2). The present case report exhibit a cystic lesion with both luminal and mural component.

Bilateral Calcifying Odontogenic Cyst: A Rare Entity

The calcifying odontogenic cyst (COC) accounts for 1 % of jaw cysts, found most commonly as central lesion. The COC usually manifests itself as a painless, slow growing swelling, anterior to the first molar region. Radiographically it appears as a well-defined, unilocular radiolucency, and may have a radiopaque mass in its center. Majority of the cases appear before the fourth decade of life. The COC is found rarely in patients in the first decade of life. Histopathological features include a cystic lining demonstrating characteristic "Ghost" epithelial cells with a propensity to calcify. Here we report the unusual occurrence of a case of 8 year child diagnosed with bilateral COC on right and left side of mandible.

A 44-year analysis of ghost cell odontogenic tumour subtypes in an Iranian population

The objectives of our study were to evaluate the relative frequency of calcifying cystic odontogenic tumours (CCOTs), dentinogenic ghost cell tumours (DGCTs) and ghost cell odontogenic carcinomas (GCOCs), collectively known as ghost cell odontogenic tumours (GCOTs), in an Iranian population and to classify these lesions according to the 2005 WHO guidelines. Clinical/demographic data were recorded for all COCs referred to our Department from 1966 to 2010. H&E-stained slides were re-evaluated by two observers and all cases were reclassified according to the 2005 WHO guidelines. The male to female ratio of 37 retrieved COCs was 1.6 with most cases occurring intraosseously and in the second decade of life. Involvement of the mandible was significantly higher than the maxilla (P = 0.033). Histopathologically, most lesions demonstrated a cystic morphology and there were no GCOCs among our cases. Eight cases were followed for 4-20 years and 3 of them showed a total of 5 recurrences. Considering the variations among clinicopathologic reports of COC from different countries, presentation of epidemiologic data based on a universally accepted classification system would be extremely helpful in providing a better understanding of this lesion and comparing results between studies.

A rare presentation of hybrid odontogenic tumor involving calcifying cystic odontogenic tumor and plexiform ameloblastoma

A hybrid odontogenic tumor comprising two distinct lesions is extremely rare. We presented a hybrid odontogenic tumor composed of a calcifying cystic odontogenic tumor (CCOT) and a plexiform ameloblastoma. This tumor was observed in the anterior area of the mandible of a 17-year-old Indian male. Masses of ghost epithelial cells with the characteristics of CCOT were seen in the lining of the cyst. The odontogenic epithelia with the features of plexiform ameloblastoma were also observed.

Calcifying cystic odontogenic tumor and adenomatoid odontogenic tumor: radiographic evaluation

OBJECTIVES

The aim of this study was to describe the radiographic features of calcifying cystic odontogenic tumors (CCOTs) and adenomatoid odontogenic tumors (AOTs) and to compare the radiographic findings for these 2 lesions.

STUDY DESIGN

We retrospectively reviewed radiographs of CCOTs and AOTs. Location, border, relationship of the lesion with the impacted tooth, calcification patterns, tooth displacement, and root resorption were evaluated.

RESULTS

Nine CCOTs and 8 AOTs were reviewed. Most CCOTs and AOTs had smooth borders. Three CCOTs and 7 AOTs enclosed impacted teeth. Of these cases, the radiolucencies of 3 CCOTs and 1 AOT were attached to the impacted teeth at the cementoenamel junctions. Three AOTs enclosed more portions of the roots, and the other 3 AOTs enclosed the entire teeth. Calcification in CCOTs appeared as a thin radiopaque line (2 cases) and discrete radiopaque foci (1 case), whereas AOTs had numerous dispersed or clustered radiopaque foci (4 cases).

CONCLUSIONS

Radiolucency with numerous radiopaque foci (particularly when the radiolucency surrounds a portion of the root or entire tooth) is suggestive of an AOT rather than a CCOT.

Distintas manifestações do tumor odontogênico cístico calcificante

O tumor odontogênico cístico calcificante normalmente se manifesta como uma massa indolor, de crescimento lento, que acomete tanto a maxila como a mandíbula, tendo predileção pelo segmento anterior (área dos incisivos e caninos). Geralmente, ocorre em adultos jovens, na terceira a quarta década de vida, sem preferência por gênero. Imagens de tomografia computadorizada revelaram características importantes não detectadas na radiografia panorâmica, tais como fenestração, calcificação e estruturas dentiformes. A característica microscópica típica dessa lesão é a presença de células epiteliais aberrantes anucleadas, em quantidades variáveis, denominadas "células fantasmas". Também se pode encontrar dentina displásica e, ocasionalmente, os cistos estão associados a tecido dentário duro, semelhante ao odontoma. O tratamento do tumor odontogênico cístico calcificante incluiu simples enucleação e curetagem. O objetivo deste trabalho foi mostrar duas manifestações diferentes do tumor odontogênico cístico calcificante, em que a tomografia computadorizada, associada às características clínicas, foi ferramenta importante para o diagnóstico, o planejamento cirúrgico e o acompanhamento dos pacientes.

Odontoma associated with calcifying cystic odontogenic tumor in deciduous dentition: case report

BACKGROUND

Initially described by Gorlin et al. in 1962, the calcifying cystic odontogenic tumor (CCOT) may be associated with unerupted teeth, ameloblastomas, adenomatoid odontogenic tumors, and, in many cases, with odontomas. It is rare in patients in the first decade of life, particularly involving deciduous teeth. Surgery is the treatment of choice, with low recurrence rates.

CASE REPORT

We present a clinical case of CCOT associated with odontoma and a missing deciduous tooth in a 3-year-old female patient. The lesion was removed under general anesthesia. The patient has been followed up for 1 year, and no recurrence was found. This appears to be the first report in such a young age.

Calcifying cystic odontogenic tumour: CT imaging

OBJECTIVES

Calcifying cystic odontogenic tumour (CCOT) is a rare disorder of the jaw. A comparison between conventional radiographs and CT images in CCOTs has not been reported. The purposes of this study were to analyse conventional radiographs and CT images of CCOTs, establish CT images of CCOTs and assess the utility of CT in the diagnosis of CCOTs.

METHODS

Nine patients with a histopathologically confirmed CCOT who had both conventional radiographs and CT images were enrolled.

RESULTS

CT was superior to conventional radiographs in detecting buccolingual expansion, odontomas and radio-opaque bodies.

CONCLUSION

The characteristic CT appearances of CCOT were that radio-opaque bodies were typically located in the periphery of the lesion and the shape of radio-opaque bodies was linear and/or spotted. CT was useful in diagnosing a CCOT.

Calcifying ghost cell odontogenic cyst: report of a case and review of literature

The calcifying ghost cell odontogenic cyst (CGCOC) was first described by Gorlin et al. in 1962. Calcifying ghost cell odontogenic cyst is comparatively rare in occurrence, constituting about 0.37% to 2.1% of all odontogenic tumors. The most notable features of this pathologic entity are histopathological features which include a cystic lining demonstrating characteristic "Ghost" epithelial cells with a propensity to calcify. In addition, the CGCOC may be associated with other recognized odontogenic tumors, most commonly odontomas. There are variants of CGCOC according to clinical, histopathological, and radiological characteristics. Therefore a proper categorization of the cases is needed for better understanding of the pathogenesis of each variant. Here, we report a classical case of calcifying odontogenic cyst along with a brief review of literature.

[Mixed odontogenic tumours]

Mixed odontogenic tumors include all tumors of the teeth both epithelial and mesenchymatous. Most of these tumors are rare (ameloblastic fibroma, ameloblastic fibro-odontoma and fibrodentinoma, odontoameloblastoma, calcified odontogenic cyst). Other tumors such as odontoma are frequent. They have in common a benign aspect, their often-fortuitous observation, a higher rate in the young adult and surgical treatment by complete exeresis preventing recurrence. They present a radiolucent lacuna but appear different depending on the presence or not of intralesional calcifications revealing the production of more or less mature dental tissue. The diagnosis may be confirmed only by an anatomopathological examination, along with clinical and radiological observations.

Computerized tomography observation of a calcifying cystic odontogenic tumor with an odontoma: case report

The calcifying cystic odontogenic tumor is a rare benign odontogenic lesion. This report documents a case of this lesion associated with odontoma arising from the anterior maxilla in a 14-year-old boy. The diagnosis was confirmed based on computerized tomography findings, which clearly depicted the internal structures obscured in conventional images.
