Primordial Odontogenic Tumor: Report of a Case with 10 Years Follow-Up
The primordial odontogenic tumor (POT) has recently been classified as a new entity in the WHO Classification of Head and Neck Tumours (2017). POT has been added to the section on benign mixed epithelial and mesenchymal odontogenic tumors. At the time of publication of the WHO classification 7 cases of POT had been published. Due to the small number of cases a new case of POT in a 6-year old male patient is presented. The patient presented with an osteolytic lesion in the anterior maxilla associated with odontoma-like structures that had caused retention of the central incisors. The lesion was surgically removed. Histopathology showed a mesenchymal tissue proliferation surrounded by columnar epithelium. The epithelium showed one or two layers of flat cells. In some areas reverse nuclear polarity in the cores was present. Both clinical and histopathological findings are in accordance with the diagnosis of POT. Because of the young age of the patient he was followed-up for 10 years. At present he is under orthodontic treatment for stimulation of zone growth followed by rehabilitation using dental implants.
