title: Primordial Odontogenic Tumor: Report of a Case.
abstract: Primordial odontogenic tumor (POT) was first described in 2014. It typically presents in the posterior mandible of a child or adolescent as a "dentigerous cyst-like" well-circumscribed radiolucency associated with an unerupted molar. POT consists of an ellipsoidal mass of dental papilla-like myxoid connective tissue entirely enveloped in a delicate membrane of ameloblastic epithelium. It shows features of a developing tooth with a huge dental papilla, and because it is devoid of dental hard tissue, it could be regarded a soft tissue odontoma. The lesion histologically mimics early (primordial) stages of tooth development. This report describes a case of POT and POT-like proliferations in an unrelated complex odontoma.
