“…Patients present with serious aesthetic and functional impairment and need to undergo reconstructive surgeries with radical approach [4]. The reasons for recurrence can be multifactorial such as local invasiveness of the tumour, histological type, tissue components and the treatment approach [1,3]. The objective of the present study was to evaluate the literature regarding clinical, radiographic, histopathologic features; treatment and recurrence rate of ameloblastomas and compare it to features of recurrent ameloblastomas.…”

Introduction: Ameloblastoma is an odontogenic tumour with high recurrence rate. The objective of the present study was to evaluate existing literature regarding clinical, radiographic, histopathologic features, treatment, and recurrence rate of ameloblastomas and compare it with features of recurrent ameloblastomas. Materials and methods: A systematic review was done based on the PRISMA statement. Search was performed in “Pubmed” database with search terminology “recurrent ameloblastoma”, “ameloblastoma recurrence” for articles published between 2010 and 2020. Data were extracted from full‐text articles and discussed. Results: Out of 515 articles, 16 articles fulfilled the inclusion and exclusion criteria. Data was analysed in two sections. The first with 10 publications assessed features of ameloblastoma in general and their recurrence rate while the second section evaluated features of only recurrent ameloblastomas in 6 publications. There were 234 recurrences in 936 cases with recurrence rate of 23.50%. Male predominance was noted and mandible was commonly affected. Solid/multicystic ameloblastomas formed 74.5% of the tumours and unicystic formed 23.3%. The recurrence rate after conservative treatment was 64.9% and after radical treatment was 12%. Conclusions: The main factors for recurrence were multilocular ameloblastomas, follicular histopathology and conservative treatment.

“…Histopathologic examination of the present collection showed a predominance of follicular type tumor, [22], where epithelial islands simulate enamel organs and often mimic the appearance of regular ameloblasts [12]. Also, follicular AMBLs seem to have a higher recurrence rate than the others variety [12,22,23] and have a propensity to invade the cranial vault, and this most likely relates to anatomical proximity rather than some inherent difference in tumor biology [2]. Risk factors for AMBL with intracranial involvement include the volume of the primary lesion, site, delayed diagnosis of the initial tumor, multiple local recurrences, inadequate surgical resection, a previous history of radiation/chemotherapy treatment, and plexiform histology [24].…”

Background Ameloblastoma (AMBL) is an odontogenic tumor, considered to be benign, but aggressive, whose principal risk is a recurrence. The growth can be enormous, and it can extend into the intracranial compartment with serious consequences. Purpose The intracranial involvement of AMBL is rare, and it may require an extensive surgery. Although it is a rare condition for the neurosurgeon to treat, knowing this condition can lead to a significant increase in survival for these patients. Methods A case of a 56-year-old woman presented with a history of recurrent left maxilla AMBL with intracranial extension and dural involvement of the anterior and medial cranial fossa is reported, followed by a systematic review of the literature with the aim to identify the best surgical treatment. Results A total of 32 cases were included in the qualitative analysis. Management is varied and often not described, resulting in an almost complete lack of information and indications for treatment. Radical surgery tends to yield the best outcomes, and it is recommended to have adequate surgical margins when possible. Conclusions Intracranial involvement from AMBL compartment is an uncommon manifestation of this rare pathology, but which deserves to be treated in a multidisciplinary way in order to ensure maximum surgical radicality. Recurrence reflects failure of the primary surgical resection. If recurrence is the major consideration, surgeons are encouraged to select radical surgery. Whenever a follicular-type maxillary AMBL is diagnosed, it is advisable to check for intracranial spreading and distant metastases during follow-up.
