Maxillary ameloblastoma is quite rare especially the one that outcomes facial deformity. Eighty-five percent of ameloblastoma cases happen to the mandible, mostly in the molar-ascending area. About 15% of ameloblastomas occur in maxilla. We are reporting a maxillary ameloblastoma case of an Indonesian patient. Bilateral Weber Ferguson approach was performed to facilitate total maxillectomy and ...

Ameloblastoma is an odontogenic neoplasm whose molecular pathogenesis has only recently been elucidated. The discovery of recurrent activating mutations in FGFR2, BRAF, and RAS in a large majority of ameloblastomas has implicated dysregulation of MAPK pathway signaling as a critical step in the pathogenesis of this tumor. Some degree of controversy exists regarding the role of mutations affecti...

Ameloblastomas are rare odontogenic epithelial tumors that occur mainly in the mandible. Despite their benign histologic appearance, they are locally aggressive with a high recurrence rate. However, a metastasizing ameloblastoma has been rarely reported. According to the current World Health Organization classification system, the definitive diagnosis of metastasizing ameloblastoma can only be ...

The term plexiform unicystic ameloblastoma refers to a pattern of epithelial proliferation that has been described in cystic cavity. Because of unilocular presentation, it is commonly misdiagnosed as an odontogenic cyst. However, they may often behave clinically as biologically aggressive tumors. These tumors show high incidence of cortical perforation, tooth resorption and a high rate of recur...

Peripheral ameloblastoma, a rare and unusual variant of odontogenic tumour, comprises about 2-10% of all ameloblastomas. The extraosseous location is the peculiar feature of this type of tumour, which is otherwise similar to the classical ameloblastoma. This paper describes a case of peripheral ameloblastoma in a 67-year-old female affecting the lingual alveolar mucosa of the mandibular 32-34 r...
