Treatment of a calcifying epithelial odontogenic tumour with tube decompression: a case report.

Conservative treatment of odontogenic tumours with decompression or marsupialisation is not common, but can be done successfully in those with a cystic pattern. We present a calcifying epithelial odontogenic tumour that was treated by tube decompression and subsequent enucleation.

Ameloblastoma mandibular: enfoque diagnóstico y terapéutico / Ameloblastoma of the jaws: diagnostic and terapeutic approach

El ameloblastoma se define como un tumor benigno polimórfico localmente invasivo constituido por una proliferación de epitelio odontogénico en un estroma fibroso que se clasifica dentro de los tumores benignos de epitelio odontogénico con estroma fibroso maduro sin ectomesénquima odontogénico. Constituye aproximadamente el 13% de todos los tumores odontogénicos. No presenta predilección por el sexo siendo más prevalente entre la cuarta y quinta década, aunque puede presentarse a cualquier edad, incluso en niños. Estos tumores presentan un patrón de crecimiento lento y de forma silente, sin signos precoces evidentes, afectando fundamentalmente el hueso mandibular en el 80% de los casos. La actitud terapéutica es compleja por su propensión característica a la recidiva, que surge de la posibilidad de dejar lesiones microscópicas periféricas y del eventual origen pluricéntrico que presentan este tipo de lesiones

Ameloblastoma is a polymorphic benign tumor locally invasive. It is constituted by a proliferation of odontogenic epithelium on a fibrous stroma, and it is classified into benign tumors of odontogenic epithelium with mature fibrous stroma and without odontogenic ectomesenchyme. This type of tumor constitutes approximately the 13% of all types of odontogenic tumors. it grows in both women and men between forty and fifty years old without preference, but it can also appear in people of any age (even in children). This kind of tumor affects mandibular bones and has a silent and slow growth without early signs. Ameloblastoma may be recurrent and it has multiple origins, that is why the treatment is complex and it may cause peripheral and microscopic lesions

Calcifying cystic odontogenic tumor radiographically mimicking a lateral periodontal cyst: clinical case report / Tumor odontogênico cístico calcificante mimetizando radiograficamente o cisto periodontal lateral: relato de caso clínico

The calcifying cystic odontogenic tumor (CCOT) is a rare odontogenic lesion derived from the remaining odontogenic epithelium of the maxilla or mandible. Its occurrence in the maxilla and mandible is similar, however, the canine region is the most affected when compared with other regions. The aim of this paper is to relate the case of a patient who presented a CCOT in the left region of the maxilla, between the canine and the first premolar, characterized by an increase in volume that was painful on palpation. The lesion presented a well circumscribed radiolucent radiographic image, however, presented no root resorption and radiopacities suggestive of dystrophic calcification, common signs in this tumor. With the diagnostic hypothesis of a lateral periodontal cyst, enucleation of the lesion was performed. The patient has been followed-up for around 15 months without signs of recurrence.

O tumor odontogênico císto calcificante (TOCC) é uma lesão odontogênica rara derivada do epitélio odontogênico remanescente da maxila ou mandíbula. Possui ocorrência semelhante em maxila e mandíbula, porém a região de canino é a mais afetada quando comparada com outras regiões. O objetivo deste estudo é relatar um caso de um paciente que apresenta um TOCC em região esquerda de maxila, entre o canino e o primeiro pré-molar, caracterizado com aumento de volume doloroso à palpação. Radiograficamente a lesão apresentava imagemradiográfica radiolúcida bem circunscrita, no entanto não apresentava reabsorção radicular e radiopacidades sugestivas de calcificação distrófica, sinais comuns neste tumor. Com hipótese diagnóstica de cisto periodontal lateral, foi feita enucleação da lesão. O paciente está em acompanhamento há cerca de 15 meses sem sinais de recorrência.

Persistent apical periodontitis associated with a calcifying odontogenic cyst.

AIM: To report a case of calcifying odontogenic cyst (COC) that was suggestive of apical periodontitis adjacent to the roots of the maxillary incisor teeth. SUMMARY: Tooth 21 presented with clinical and radiographic signs of secondary infection, a post within the root canal and substantial internal tooth destruction; it was scheduled for endodontic surgery. Teeth 12 and 22 were root filled following the placement of a calcium hydroxide intracanal dressing for 21 days. Three attempts at root canal disinfection in tooth 11 were unsuccessful, and a persistent purulent drainage precluded completion of root canal treatment. Surgical enucleation of the periapical lesion was undertaken and the tissues submitted for histopathological examination. A diagnosis of COC was established based on the microscopic analysis. COC is an unusual benign lesion that represents 2% of all odontogenic lesions. Depending on the stage of development, it can mimic a large lesion associated with apical periodontitis and should therefore be considered in the differential diagnosis. In the case of COC, the definitive diagnosis can only be made with histopathological analysis. KEY LEARNING POINTS: Persistent apical periodontitis may be of nonendodontic origin. * Histological examination is essential to establish the cause of persistent apical periodontitis. * Calcifying odontogenic cyst can mimic apical periodontitis.

Extraosseous calcifying odontogenic cyst: a case report and a literature review

The calcifying odontogenic cyst is an uncommon odontogenic lesion that can have intra- or extraosseous occurrence with both cystic or tumor behavior. A report of an extraosseous calcifying odontogenic cyst (ECOC) in a 57-year-old black woman is presented as well as a review of the literature about the lesion. The clinical, radiographic and histopathologic features are discussed, along with etiology and treatment.

O cisto odontogênico calcificante é uma lesão odontogênica incomum que pode ser intra ou extra-óssea, tanto com um comportamento cístico quanto com um comportamento neoplásico. Neste trabalho está sendo apresentado o relato de um caso de cisto odontogênico calcificante em uma mulher da raça negra, com 57 anos de idade, bem como uma revisão da literatura sobre a lesão. Os achados clínicos, radiográficos e histopatológicos são discutidos, assim como sua etiologia e o seu tratamento.

Cisto odontologênico calcificante: relato de 2 casos com considerações sobre o tratamento / Calcifying odontogenic cyst: report of 2 cases and treatment considerations

O presente artigo relata dois casos de cisto odontogênico calcificante, o primeiro associado a um odontoma e outro associado a um ameloblastoma. Isto modifica completamente o plano de tratamento, devido ao comportamento biológico de cada lesão associada, podendo variar de uma curetagem a um tratamento cirúrgico radical. O que evidencia a importância de um diagnóstico preciso e uma proservação criteriosa dentro da prática odontológica.

Odontogenic ghost cell tumor: a case report with cytologic findings.

Odontogenic ghost cell tumor is a rare, neoplastic form of calcifying odontogenic cyst (Gorlin cyst) whose cytologic features have not been previously reported. We present a case of odontogenic ghost cell tumor diagnosed by fine-needle aspiration biopsy (FNAB). The aspirate was characterized by (1) tissue fragments with basaloid epithelial cells, (2) "ghost" cells, (3) scattered multinucleated giant cells, (4) rare, eosinophilic, densely hyalinized "dentinoid" material in close association with the basaloid cells, and (5) calcific debris. The aspirate was diagnosed as "consistent with odontogenic ghost cell tumor." The cytologic features of odontogenic ghost cell tumor, as described, closely parallel the major histologic findings in this rare tumor. The differential diagnoses include other odontogenic tumors, squamous cell carcinoma, basaloid cell tumors of the salivary gland, and pilomatrixoma.
