Odontogenic Keratocyst Tumor: A Case Report and Literature Review  [PDF]
Akram Belmehdi, Saliha Chbicheb, Wafaa El Wady
Open Journal of Stomatology (OJST) , 2016, DOI: 10.4236/ojst.2016.67022
Abstract: First described by Philipsen in 1956, the odontogenic keratocyst is characterized by a large squamous keratinization of its border, an aggressive growth and a high recurrent rate. It is now designated by the World Health Organization as a keratocystic odontogenic tumour (KOT). Clinically, the KOT is manifested by an asymptomatic growth. Radiographically, it appears as a well-defined uni-locular or multilocular osteolytic lesion. The diagnostic approach is based on a combined analysis of the medical history, the clinical appearance and the radiographic appearance. The diagnosis may be confirmed by the anatomical pathology report. Finally, treatment consists of surgical excision and follow up is characterized by a high rate of recurrence. The authors report a case of keratocystic odontogenic tumor of the upper jaw and review the various diagnoses, therapeutics and follow up aspects of this type of tumors.
Tumor odontogenico adenomatoide: Reporte de un caso y revisión de la literatura
Reyes Fernández1,Dr.Salvador; Romero Castro2,Dra. N. Samanta;
Acta Odontológica Venezolana , 2005,
Abstract: summary the odontogenic adenomatoid tumour is clasifyed for the who as an odontogénic neoplasm with connective tissue formation, so it can contain hard tissue inside it presents as a slow growing mass and it is not much invasive but it can be similar to other more invasive lesions as the folicular cyst , ameloblastoma and others. it′s seen more frecuently in the uper cuspid area and this finding helps us in the diagnosis, and the histologic findings as duct formations is very caracteristic. in this work we made a literature revision about the clinical, radiografic and histologic findins and treatment as the diferential diagnosis and we report one case
Odontogenic Myxoma of Maxilla in an Atypical Location: A Case Report
Ghalayani P.,Jahanshahi GR.,Mohagheghiyan HR.
Journal of Dentistry , 2013,
Abstract: Odontogenic myxoma is a rare and locally invasive benign neoplasm found exclusively in jaws. It presents local invasiveness and tendency to recurrence. According to the World Health Organization (WHO), the odontogenic myxoma is classified as an odontogenic tumor of ectomesenchymal origin. The odontogenic myxoma is a rare entity found in both jaws while the mandible is involved more commonly than the maxilla. We present a kind of odontogenic myxoma in a 24-year old male that was found in an unusual location.
Odontogenic myxoma of maxilla
Sivakumar G,Kavitha B,Saraswathi T,Sivapathasundharam B
Indian Journal of Dental Research , 2008,
Abstract: Odontogenic myxoma (OM) is a rare and locally invasive benign neoplasm found exclusively in the jaws. OM commonly occurs in the second and third decade, and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. The radiographic features are variable, and the diagnosis is therefore not easy. A case of OM of the maxilla with unusual radiographic and histologic features is described in a 30-year-old male. A panoramic radiograph revealed a well-demarcated, multilocular radiolucent lesion with ′tennis racket′ appearance involving maxillary antrum. The histopathology showed loosely arranged spindle-shaped stellate cells and few areas of inactive odontogenic epithelium in a mucoid intercellular substance.
Calcifying epithelial odontogenic tumor: Report of two cases
Mandal Shramana,Varma Kachnar,Khurana Nita,Mandal A
Indian Journal of Pathology and Microbiology , 2008,
Abstract: Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign odontogenic tumor. It constitutes 0.4-3% of all odontogenic tumors. There is only a single case, which has been reported in the Indian literature that too in cytology. Microscopically, these are composed of large sheets of epithelial cells, amorphous amyloid-like material and calcification. Although these lesions are benign, they can be locally aggressive, but malignant transformation and metastasis is rare. Considering its locally aggressive nature, appropriate management and long-term follow-up is recommended. We describe two cases of CEOT involving the hard palate and leading to facial alterations.

Revista Cubana de Estomatolog?-a , 2010,
Abstract: the adenomatoid odontogenic tumor is an uncommon neoplasm derivative of the odontogenic epithelium containing canalicular structures with inductor modifications of variable intensity in the conjunctival tissue. it is a slow growth lesion and no much invasive but that may to be similar to other odontogenic lesions more aggressive including the dentigerous cyst and the ameloblastoma among others. its classical location (upper canine area) guides us to diagnosis and its duct histological pattern is very typical of this tumor. other tumors included in this group are the ameloblastic fibroma, the ameloblastic odontoma, the calcified odontogenic cyst and composed and complex odontomas. this group of lesions may or not to have formations of hard tissue inside. thus, authors present the case of a patient presenting with this type of tumor making a histopathology study, a literature review on this benign odontogenic tumor and its clinical radiographic features, treatment, as well as the differential diagnoses to be into account.
Mixoma odontogénico

Revista Cubana de Estomatolog?-a , 2009,
Abstract: an odontogenic myxoma is a uncommon benign neoplasm of a gelatinous and solid consistency, of lengthy growing with a infiltration potential producing an cortex expansion of with and extend bone destruction and a high rate of relapse. its origin is ectomesenchymal, probably derived from dental organ. there is not a particular sexual preference, but a slight one by be present in mandible and generally asymptomatic. this is the case of a female white patient aged 16, with health backgrounds referred to maxillofacial consultation due to an of right hemifacial increase without another accompanying symptomatology. at physical examination there is an increase in volume of right maxillary region. in computerized axial tomography (cat) a hyperdense lesion occupying all right maxillary sinus with areas of higher density without affecting the orbit floor bone. under nasotracheal general anesthesia a hemimaxillotomy was carried out, tumor removal and obturator immediate prosthesis placing. at a year of clinical course and radiography definitive prosthesis was placed without tumor relapse.

Abstract: the ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. it occurs predominantly in children and young adults with no sex predilection and locates most often in the posterior segment of the mandible. a painless swelling is the most common clinical sign. radiologically, ameloblastic fibro-odontoma shows a circumscribed radiolucency, which contains radio-opaque foci of various sizes and shapes. histological examination reveals a fibrous soft tissue, islands of odontogenic epithelium and a disordered mixture of dental tissues. the tumor produces enamel or enamel matrix, dentin and cementum. the treatment of ameloblastic fibro-odontomas usually consists of enucleation or surgical curettage, which is possible due to their benign biological behaviour.
Tumor odontogenico adenomatoide: Reporte de un caso y revisión de la literatura
Dr.Salvador Reyes Fernández1,Dra. N. Samanta Romero Castro2
Acta Odontológica Venezolana , 2005,
Abstract: El Tumor Odontogéncio Adenomatoide es una lesión clasificada por la OMS dentro de los tumores odontogénicos con participación del ectomesénquima, ya que puede contener, además del epitelio, tejido calcificado en su interior (1). Es una lesión de crecimiento lento y poco invasiva pero que se puede asemejar a otras lesiones odontógenas de mayor agresividad como el quiste dentígero y el ameloblastoma entre otros. Su localización clásica (área de caninos superiores) nos orienta al diagnóstico y su patrón histológico ductiforme es muy propio de este tumor (1). Se hace una revisión de la literatura acerca de este tumor odontogénico benigno, sus características clínicas, radiográficas, tratamiento, así como los diagnósticos diferenciales que se deben tener en cuenta, y se reporta un caso Resumo O tumor Odontogéncio Adenomatoide é um ferimento classificado pelo OMS dentro dos tumores odontogénicos com participa o de ectomesénquima, desde que pode conter, além ao epitelio, o tejido calcificado no seu interior(1). é um ferimento invasivo pequeno do crescimento lento e, mas aquele pode serás semelhou-se a outros ferimentos dos odontógenos de um agressividade maior como quisto e o ameloblastoma dentígero entre outro.
