A rare primordial odontogenic tumor in a pediatric patient

Primordial odontogenic tumor (POT) is a rare, benign pediatric lesion that was first included in the 2017 edition of WHO Classification of Head and Neck Tumours. At that point, only 7 cases had been described in the literature; a total of 23 cases have been reported to date. This case report adds to that total by describing a case of POT in a 12-year-old girl and reviews the characteristics of this neoplasm in order to better characterize its clinical, radiographic, and histologic features and increase dentists' awareness of POT. The presence of calcifications within the lesion was reported in 4 of 23 previous cases, and calcifications were also observed in the current case. The presence of calcifications in POT is uncommon and may make radiographic diagnosis more challenging. Treatment of POT is simple excision, and recurrence after excision is rare. Accurate diagnosis is essential, as there has been at least 1 report of overtreatment involving mandibulectomy.
