Papilliferous Keratoameloblastoma: A Rare Case Report

Ameloblastoma is true odontogenic tumor of epithelial origin, which is described as locally aggressive with varying chances of recurrence. It is believed to derive from enamel organ, remnants of dental lamina, lining of odontogenic cysts, or basal cells of oral epithelium. Radiologically, it may present as unilocular or multilocular radiolucency commonly. Although conventional ameloblastoma presents typical histological features as described by Vickers and Gorlin, few unusual variants have been reported with different histological patterns. However, the clinical and biological behavior of these lesser known variants has not been established yet due to the scarcity of cases reported. Here, we report an extremely rare case of papilliferous ameloblastoma in a young male patient with 2-year follow-up and presenting with unusual histological presentation than conventional ameloblastoma.
