Samenvatting
Ameloblastoma is the most common odontogenic tumour. The tumour has been described as a benign but locally invasive polymorphic neoplasm. Hybrid lesions have been described, which combine histological features of desmoplastic and conventional ameloblastoma. The hybrid ameloblastoma is rare and only few cases have been reported worldwide. We present two cases seen from a review of 195 ameloblastoma cases seen over a ten year period. The cases presented with clinical features of the conventional ameloblastoma such as buccolingual bone expansion and multilocular radiololucency. Larger clinical series of hybrid ameloblastoma need to be reviewed in order to better characterize the clinical behaviour, aggressiveness and prognosis of this rare variant of ameloblastoma.

Résumé
L’ameloblastome est une tumeur odontogenique le plus commun. La tumeur a été décrit comme bénigne mais localement un néoplasme polymorphique invasive. Les lésions hybrides ont été décrites, laquelle combine les caractéristiques du demoplastique et de l’ameloblastome conventionnelle. L’hybride d’ameloblastome est rare et seulement sauf quelques cas ont été rapports dans le monde entière. Nous présentons deux cas diagnostiqués d’une revue de 195 cas d’ameloblastome vus pendant 10 ans. Les cas présentaient des signes cliniques de l’ameloblastome conventionnelle telle que l’expansion de l’os bucco-lingual et de radiololucence multiloculaire. Un nombre important de cas clinique d’hybride d’ameloblastome doit être revu afin de mieux caractériser le comportement Clinique, agressivité et le pronostic de ce cas rare d’ameloblastome.
