“…This condition is identified mainly in the second and third decades of life, with no apparent gender predilection. CCOT can be found in the maxilla and mandible, with a predilection for the anterior region, 64 especially in the incisor and canine regions. 2 Clinically, this tumor usually is a painless, slow-growing lesion that may present bone expansion, and may be associated with an unerupted tooth, because of its occasional involvement with the crown of a tooth.…”

Differential diagnosis and clinical management of periapical radiopaque/hyperdense jaw lesions

Great attention has been given to the study of radiolucent periapical lesions to avert possible misdiagnosis of apical periodontitis associated with certain radiolucent non-endodontic lesions. However, there are a significant number of radiopaque lesions found in the periapical region, which could be equally relevant to endodontic practice. The diagnosis and management of these radiopaque/hyperdense lesions could be challenging to the endodontist. These bone alterations could be neoplastic, dysplastic or of metabolic origin. In the context of the more widespread use of cone-beam CT, a detailed review of radiopaque inflammatory and non-inflammatory lesions is timely and may aid clinicians perform a differential diagnosis of these lesions. Distinguishing between inflammatory and non-inflammatory lesions simplifies diagnosis and consequently aids in choosing the correct therapeutic regimen. This review discusses the literature regarding the clinical, radiographic, histological and management aspects of radiopaque/hyperdense lesions, and illustrates the differential diagnoses of these lesions.

“…Histologically, the CCOT presents like a cystic cavity with covered with non-keratinized stratified squamous epithelium of varying thickness, composed of basal layer of columnar arrangement in palisade, similar to ameloblasts. It is possible to observe layers of eosinophilic cells, also called "ghost cells", besides acellular calcified matrix dentinoid or bone 4,9 .…”

The calcifying cystic odontogenic tumor (CCOT) is an uncommon pathology, representing about 2% of all odontogenic cysts and tumors. Generally, is presented as slow growth, asymptomatic, without predilection of gender or location. The most common radiographic presentation is radiolucent image with radiopaque areas, especially in the lesion periphery, unilocular, expansive and well-defined margin. The purpose of this report is to describe the case of a 16-year-old boy with a painless and progressive increase of volume on the face, which started 7 months ago. In oroscopy, we observed an expansive increase of volume in right maxilla, extending from premolars to molars on the same side. In computed tomography, it was possible to observe an unilocular, expansive image in right maxilla. After incisional biopsy, the histopathological analysis evidenced epithelial neoplasia of odontogenic origin that presents cystic portions and solid portions. In the cystic portions, there is an epithelial lining which basal cells are cuboidal or cylindrical arrangement in palisade, presence of ghost cells and dystrophic mineralization, confirming the diagnosis of calcifying cystic odontogenic tumor. Excision and curettage were performed under general anesthesia. The excised tumor was analyzed, confirming the diagnosis of CCOT and the patient has been in clinical and radiographic follow-up for a period of 5 years, without signs of relapses.

“…The authors suggested that marsupialization could be used as a preliminary treatment option for CCOT to minimize damage to the anatomical structures. Sakai et al emphasized the importance of marsupialization before total surgical removal in young patients with large CCOT lesions8.…”

“…Both intraosseous and extraosseous forms of the lesion are found in the maxilla and mandible with approximately the same probability6, and these lesions mostly affect the incisor and canine areas. This lesion can also involve the posterior maxilla, but only few such cases have been reported78.…”

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.
