“…Of the 10 patients, seven showed no evidence of disease after surgery and/or radiation therapy, with follow-up ranging from 1 to 10 years. [28] Additional evidence suggesting the value of radiation therapy in treating the ameloblastoma has been reported by Gardner. [29]…”

Ameloblastic carcinoma (AC) is a rare primary odontogenic tumor that has histological features of both ameloblastoma and carcinoma. A total number of 92 case reports speak about its rare incidence, affecting mostly the mandible as a locally destructive lesion. The maxilla is affected even more rarely as only 35 cases have been reported until 2012 in scientific literature. The clinical course of AC is generally aggressive, with extensive local bone destruction. The most common clinical features include swelling, pain, trismus, significant bone resorption with tooth mobility, dysphonia and intraoral fistula. We report two cases of AC with aggressive behavior.

“…This belief was supported by literature published in premegavoltage days of radiation therapy [4]. Advancement in radiotherapy resulted in cases of ameloblastoma responding to them, and respectively, several articles reported their success [4], [5], [6], [7].…”

IntroductionAmeloblastomas are rare head and neck tumors, and yet the most common odontogenic neoplasms. They account for 1% and 11% of all head and neck and odontogenic tumors respectively. Embryologically, they originate from remnants of odontogenic epithelium. Their aggressive, destructive nature, as well as their anticipated high rate of recurrence, even after en bloc resection, poses a surgical predicament.PresentationWe present a case of a 56 year-old Asian female with a multi-recurrent invasive ameloblastoma. Initially, the lesion was mandibular in location for which she underwent a mandiblectomy. Later on, she presented with a maxillary ameloblastoma with invasion of both the anterior wall of the maxillary sinus and the floor of the orbit. The patient was operated twice and histopathology confirmed a cystic type recurrent ameloblastoma. A year later, she came with recurrent maxillary ameloblastoma and a maxillectomy was done. However, histopathology revealed a follicular ameloblastoma. Three years later, she presented with a retro-orbital ameloblastoma with infiltration to the temporal muscles. The patient was operated and the histopathologic examination revealed a partially cystic lesion with no malignant transformation.ConclusionThis case discusses available treatment options and emphasizes on the importance of long-term patient follow-up due to the biological behavior of ameloblastoma.

“…Reynolds a publie le premier cas d’améloblastome irradié et il a proposé la radiothérapie pour les tumeurs localement avancées non opérables ou en cas de refus de la chirurgie [6]. Ainsi qu’en 1984 Atkinson a publié une série de patients traités par radiothérapie avec une bonne évolution [7]. Depuis lors, d’autres observations sur le rôle de la radiothérapie dans le traitement curatif de l’améloblastome ont été publiés concernant des cas d’améloblastome mandibulaire ayant bien répondu à une radiothérapie externe de 60Gy [8].…”

L’améloblastome est une tumeur odontogène bénigne à caractère agressif qui nécessite un diagnostic précoce et un traitement adéquat. Son site habituel est la mandibule et la chirurgie radicale demeure le traitement de référence. Nous rapportons le cas d’un améloblastome à localisation sinusienne maxillaire localement très avancé que nous avons traité par radiothérapie conformationnelle avec modulation d’intensité. L’évolution a été marquée par une rémission de la maladie avec un recul de 24 mois. La localisation maxillaire d’un améloblastome est rarement décrite, diagnostiquée à un stade tardif le plus souvent où la chirurgie optimale est impossible. A travers cette observation nous démontrons que la radiothérapie constitue une véritable alternative thérapeutique dans les formes évoluées et inopérables des améloblastomes.
