Recurrent Primordial Odontogenic Tumor: Epithelium-Rich Variant

Primordial Odontogenic Tumor; Archival Review of 19380 Cases in a 55-Year Retrospective Study

“…The follow up range was between 3 months to 20 years (Mosqueda-Taylor et al, 2014;Almazyad et al, 2018). There was one case of recurrence of POT after 4 years follow up (Almazyad et al, 2022). We did not see any evidence of recurrence either after more than 6 years follow up of the patient.…”

“…We did not see any evidence of recurrence either after more than 6 years follow up of the patient. This only recurrent case of POT is the first epithelium rich variant (Almazyad et al, 2022). The different clinical behavior of this POT may be associated to unusual histopathologic features of the reported case and further evaluation is mandatory.…”

“…To date, 26 cases has been reported in literature (Almazyad et al, 2022). The aim of this study was to determine the possible presence of primordial odontogenic tumor in the previously diagnosed cases with myxoid stroma.…”

Primordial odontogenic tumor with prominent calcifications

“…The lesions varied in size, with the largest diameter ranging from 0.5 cm to 9.0 cm. Except for one case reported by Almazyad et al [2], there was basically no instance of recurrence within follow-up periods ranging from 6 months to 20 years.…”

“…Compared with POT, odontogenic myxoma is not covered by epithelium, and invariably shows infiltrative growth. Almazyad et al [2] reported a case of POT showing extensive epithelial proliferation that recurred four years after surgery. It exhibited apparent perforations of the buccal and lingual cortical plates.…”
