Tratamento cirúrgico de ameloblastoma mandibular

Ameloblastomas are benign, invasive locally and highly recurrent. It is an odontogenic tumor, characterized by the proliferation of epithelial ameloblastic in a fibrous stroma. This paper reports a case of mandibular ameloblastoma, in patients 27 years of age without pain with developments around 4 years, with about 20 mm at its greatest extent, sessile base and surface coatings full. The treatment of choice was the surgical conservative

Odontoma composto: relato de caso clínico

Os odontomas são os tipos mais comuns de tumores odontogênicos, sendo sua constituição principalmente de esmalte e dentina, com quantidade variável de cemento e polpa. Apresenta relação com dentes inclusos e sua etiopatogenia é desconhecida. Radiograficamente pode ser classificado como composto ou complexo. Acomete com mais frequência pacientes entre a primeira e segunda década de vida, e não há predileção por sexo. Localiza-se principalmente em região anterior de maxila, assintomático e tem associação com dentes inclusos e supranumerários. Neste trabalho relatamos um caso clínico, cuja paciente foi encaminhada para avaliação devido a ausência do dente 33. O diagnóstico clinico-radiográfico inicial foi de odontoma composto. Realizou-se a remoção cirúrgica da lesão e do dente incluso tendo o exame histopatológico confirmado o diagnóstico de odontoma composto.

Tumor odontogênico de células granulares

Introduction: the granular cell odontogenic tumors are an uncommon neoplasm with benign clinical behavior. The lesion occurs over a wide age range with a typically predilection for the mandibular canine and molar regions. Aim: present a granular cell odontogenic tumor literature review. Conclusions: the tumor don’t present an aggressive biological behavior although recurrences can occur. The lesion is treated by conservative surgery with curettage and enucleation as election procedures.

Immunolocalization of podoplanin in benign odontogenic tumours with and without ectomesenchyme

Objectives: To investigate podoplanin expression in epithelial odontogenic tumours with and without ectomesenchyme and verify the association between its immunoexpression and proliferative activity in keratocystic odontogenic tumours (KCOTS) and orthokeratinized odontogenic cysts (OOCs). Design: Eight ameloblastomas, nine adenomatoid odontogenic tumours, twenty KCOTS, five OOC, one calcifying epithelial odontogenic tumour, two ameloblastic fibromas, four ameloblastic fibro-odontomas and five calcifying cystic odontogenic tumours were immunohistochemically analysed with anti-podoplanin antibody. For KCOTS and OOC, the cell proliferation index was determined with Ki-67 immunostaining and compared by Spearman correlation coefficient. Results: Podoplanin was expressed in the peripheral odontogenic epithelium of most tumours. Ectomesenchyme was negative, except for odontoblasts. KCOTS exhibited positive podoplanin expression while in OOC it was absent/weak. There was statistically significant correlation ( p = 0.006) between podoplanin expression and cellular proliferation index of KCOTS and OOC. Conclusion: Podoplanin seems to be related to the proliferative activity of KCOTS and may have a role in the process of local invasion of odontogenic tumours with and without ectomesenchyme

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

Tratamiento conservador de tumor epitelial odontogénico calcificante asociado al canino inferior retenido: relato de caso clínico

The calcifying epithelial odontogenic tumour is a rare benign odontogenic neoplasm that accounts for approximately 1% of all odontogenic tumours. They are mainly located in the premolar/molar mandibular region, and are associated with an unerupted molar tooth. We present a literature review of the clinical, radiographic, pathological findings and treatment options of the calcifying epithelial odontogenic tumour, as well as describing the case of an calcifying epithelial odontogenic tumour associated with an impacted right mandibular in a 32-year-old male patient, who was treated conservatively, without no sign of recurrence of the lesion after five years.
