Granular cell ameloblastoma is classified as a histological subtype of solid/multicystic ameloblastoma. Usual granular cell ameloblastoma is histologically characterized by granular changes of stellate-like cells located in the inner portion of the epithelial follicles. Here we report a case of another type of granular cell ameloblastoma, showing predominant anastomosing double-stranded trabecu...

In this study, proliferating cell nuclear antigen (PCNA) and p53 protein expressions were analyzed in 16 cases of ameloblastoma and 8 cases of adenomatoid odontogenic tumor (AOT). The cases of ameloblastoma consisted of solid type tumors and histologic arrangements of different subtypes were observed. In some specimens, more than one histologic subtype was identified in the same lesion, and eac...

OBJECTIVE Molecular characterization of ameloblastoma has indicated a high frequency of driver mutations in BRAF and SMO. Preclinical data suggest that Food and Drug Administration-approved BRAF-targeted therapies may be immediately relevant for patients with ameloblastoma positive for the BRAF V600E mutation. METHODS A neoadjuvant treatment regime of dabrafenib was given to a patient with re...

Ameloblastoma is a benign epithelial odontogenic tumor and is the most commonly encountered odontogenic tumor in the jaws. Histologically, ameloblastomas occur in different patterns, including plexiform pattern and follicular pattern. "Hybrid" lesion of ameloblastoma is a tumor variant in which histologically, areas of follicular or plexiform ameloblastoma coexist with characteristic areas of a...

Granular cell ameloblastoma is a rare condition, accounting for 3.5% of all ameloblastoma cases. The granular cell ameloblastoma, in most instances is found as an admixture with other histologic patterns, particularly the follicular subtype. A 58 year old male patient reported with a swelling in the lower left posterior region of the face since 2 years. Orthopantomograph showed radiolucency ext...

Background. Ameloblastoma is the most common odontogenic tumor. It represents about 1% of all tumors of the jaw. Extragnathic location of the ameloblastoma is typical and extremely rare. Case Report. We report a case of ameloblastoma of the nasal septum origin, causing nasal obstruction. According to our information, this is the first reported case of ameloblastoma coming from the nasal septum ...

Desmoplastic ameloblastoma is a rare variant of benign odontogenic tumors. Our objective was to describe the clinical and pathological features of desmoplastic ameloblastoma. Three cases of desmoplastic ameloblastoma that were treated in the authors’ department were reviewed and analyzed along with radiological and histological data. The findings obtained from pathological examinations of two s...

Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined cor...
