A New Look at the History of Peripheral Ameloblastoma.

Peripheral ameloblastoma (PA) is a prototype form of extraosseous odontogenic tumor. As knowledge of PA has accumulated on the basis of more than 200 cases reported worldwide over a 60-year timeframe, it is important to comprehend the historical evolution of this entity. In 2018, we summarized the American history of PA, stressing the important early strides made by Bloodgood in 1904 with his many original observations of the "epulis form of ameloblastoma". During the preparation of our previous report, we were able to find several earlier and interesting descriptions in the literature. This review covers the early history of PA since the nineteenth century, chronologically focusing on meritorious articles published in the United States and Europe.
