Abstract:
Primordial odontogenic tumor (POT) is a rare mixed odontogenic tumor composed of primitive ectomesenchyme similar to the dental papilla. The outer surface consists of columnar/cuboidal odontogenic epithelium similar to the inner enamel epithelium, and there is no hard tissue formation. Until now, 27 cases have been reported in the English literature. This article describes the clinicopathological characteristics of one case of POT, representing the oldest patient (aged 26 years) reported to date.
