Abstract [en]

The purpose was to integrate the available data published on desmoplastic ameloblastoma (DA) into a comprehensive analysis of its clinical/radiographic features. As it is not clear if the hybrid ameloblastoma has a unique biological behavior, the clinical/radiographic features of conventional DA with the hybrid variant were compared. An electronic search was undertaken in May/2019. Eligibility criteria included publications having enough clinical/radiographic/histological information to confirm the diagnosis. 128 publications reporting 285 DAs were included (246 central non-hybrid, 33 central hybrid, 6 peripheral). There was a statistically significant difference between non-hybrid and hybrid cases concerning lesion location, radiographic limits and size. In contrast to non-hybrid tumors that showed similar distribution in mandible and maxilla, a highly predominant mandible location was observed in the hybrid tumors. Also, non-hybrid lesions more often showed ill-defined radiographic margins, and were larger tumors than hybrid DAs. Enucleation with an additional therapy (either curettage or peripheral osteotomy) or resection led to a lower recurrence risk in comparison to curettage or enucleation without additional therapy. Location of the lesion and type of treatment are related to tumor recurrence. There are important differences in location and radiographic limits between hybrid and non-hybrid DAs, which support their classification as distinct lesions.
