Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. It is clinically characterized as a painless-slow-growing tumor that affects the maxilla as well as the mandible, and generally occurs in young adults in the third or fourth decade of life. Herein, we present the case of a 16-year-old Japanese boy who showed a CCOT in the maxillary sinus. Panoramic radiography showed a unilocular lesion in the left maxillary sinus. Computed tomography showed an approximately 5-cm well-defined unilocular expansile lesion with multiple radiopaque calcific specks, arising from the left maxillary alveolar ridge. The lesion was surgically removed, under general anesthesia, and the patient was followed up for 3 years after the surgery, and there have not been any signs of recurrence.

“…In 2005, the World Health Organization Classification of Head and Neck Tumors reclassified the lesion as an odontogenic tumor and gave it the name of "calcifying cystic odontogenic tumor" (CCOT) [2]. CCOT is a rare lesion that represents about 2% of all odontogenic pathological changes in the jaw [3][4][5]. It is clinically characterized as a painless, slow-growing tumor, which equally affects the maxilla and mandible, has a predilection for the anterior region of the jaw and usually arises intraosseously, although it may also occur extraosseously.…”

“…Radiographically, CCOT may appear as an unilocular or multilocular radiolucent area with either well-circumscribed or poorly-defined margins that also may be observed in association with unerupted teeth [3,7]. Calcification is an important radiographic feature for the interpretation of CCOT, but is detected in only approximately half of the reported cases [9].…”

The calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. At that time, it was classified as a cyst related to the odontogenic apparatus, although it was later renamed as a calcifying cystic odontogenic tumor by the WHO calcification in 2005 due to its histological complexity, morphological diversity and aggressive proliferation [2]. Here, we describe a case of a calcifying cystic odontogenic tumor in a 4-year-old boy. The lesion was surgically removed, and the histopathological examination revealed it to be a cystic tumor with ghost cells, a stellate reticulum and small amount of dentinoid tissue in the cystic wall.

“…It generally affects young adults in the third to fourth decades, without gender predilection (5)(6)(7)(8) . Radiographically, radiolucent unilocular and, occasionally, multilocular images are seen with wellcircumscribed limits containing diffuse opacification areas, associated to impacted or unerupted teeth or other odontogenic tumor (4,8,9) . Histologically, CCOT is usually composed of a cystic cavity with fibrotic capsule lined by an odontogenic epithelium.…”

The calcifying cystic odontogenic tumor normally presents as a painless, slow-growing mass, involving both maxilla and mandible, primarily the anterior segment (incisor/canine area). It generally affects young adults in the third to fourth decades, with no gender predilection. Computerized tomography images revealed important characteristics that were not detected by panoramic radiography, such as fenestration, calcification and tooth-like structures. The typical microscopic feature of this lesion is the presence of variable amounts of aberrant epithelial cells, without nuclei, which are named "ghost cells". In addition, dysplastic dentine can be found and occasionally the cyst can be associated with an area of dental hard tissue formation resembling an odontoma. The treatment for calcifying cystic odontogenic tumor involves simple enucleation and curettage. The purpose of this article is to present two different manifestation of calcifying cystic odontogenic tumor in which computerized tomography, associated to clinical features, served as an important tool for diagnosis, adequate surgical planning and follow-up of patients.Keywords: Odontogenic cyst, calcifying; Odontogenic tumors; Case reports RESUMO 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.
