“…One case fulfilled the criteria for POT and therefore was reclassified as such. This case was presented in the 2013 Congress of the Brazilian Society of Oral Medicine and Pathology [7] with an initial diagnosis of immature complex odontoma with areas of ameloblastic fibroma with induction. The clinical and radiographic data were available in the charts of the patient.…”

“…However, unlike developing odontomas, POT tend to show a higher potential for continuous growth, with considerable cortical bone expansion and limited production of hard dental tissue, indicating a neoplastic nature. The present case was formerly diagnosed as "immature complex odontoma with areas of ameloblastic fibroma with induction" [7], but the diagnosis of POT was achieved after retrospective identification of the criteria first proposed by Mosqueda-Taylor et al [1] for this truly new odontogenic tumor. We have reviewed the features of 12 cases of POT previously reported in the literature and added this retrospectively discovered case of POT from 150 cases of odontogenic tumors in children diagnosed in a Brazilian Oral Pathology laboratory over the last 50 years.…”

Primordial odontogenic tumor (POT) was recently recognized in the 2017 World Health Organization (WHO) Classification as a distinct mixed odontogenic tumor most commonly observed in the posterior mandible of young patients. POT appears as an expansile radiolucency associated to an unerupted tooth. The aim of the present study was to perform a retrospective microscopic evaluation of pediatric odontogenic tumors diagnosed in an Oral Pathology Laboratory from Rio de Janeiro-Brazil, in order to reclassify potential cases as POT. From 150 cases of odontogenic tumors in children diagnosed in the last 50 years, one case filled the criteria for POT, being therefore better diagnosed as such. The patient was in the first decade of life and presented a well-defined expansile tumor in the posterior mandible, which had been initially diagnosed as immature complex odontoma. To the best of our knowledge, only 12 cases of POT have been reported in the English-language literature. We herein present an additional case of POT and review of its clinicopathological findings is offered.
