"Hybrid" ameloblastoma: a report of two cases.
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 bucco-lingual 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.
