BACKGROUND Ameloblastomas are rarely found in pregnant women, with only two cases reported in the scientific literature. We report the first case of ameloblastoma in a pregnant woman in Brazil. CASE PRESENTATION A 27-year-old white woman, 12-weeks pregnant, presented with a large mass in her right posterior mandible. Panoramic radiography revealed a lesion involving her mandibular right first...

AIM To report a small intaalveolar ameloblastoma which resembled cystic lesion, and to emphasize the value of Computed tomography (CT) in radiographic examination. BACKGROUND Ameloblastoma is a slow-growing, locally invasive odontogenic neoplasm that accounts for approximately 10% of all tumors detected in the jaws. Radiographically, those tumors are usually well-defined. Computerized tomogra...

Ameloblastoma is a locally invasive benign neoplasm derived from odontogenic epithelium and presents with diverse phenotypes yet to be characterized molecularly. High recurrence rates of 50-80% with conservative treatment in some sub-types warrants radical surgical resections resulting in high morbidity. The objective of the study was to characterize the transcriptome of ameloblastoma and ident...

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity with or without luminal and/or mural tumor growth. It accounts for 5 to 15% of all intraosseous a...

Objective: To determine the efficacy of radiotherapy in the treatment of ameloblastoma and ameloblastic

ameloblastomas are tumors of odontogenic epithelial origin. the term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. a large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

background: cyclo-oxygenase-2 (cox-2) is an early response gene that is induced by growth factors, oncogenes and carcinogens and its expression is increased in various tumors. increased expression of cox-2 plays a signifi cant role in the development and growth of tumors by interfering in biological processes such as cell division, cellular immunity, cell adhesion, apoptosis, and angiogenesis. ...
