Primordial odontogenic tumour: report of two cases

Abstract

This report describes two additional cases of POT for a total of 11 cases reported in the English language literature.

Primordial Odontogenic Tumor: Report of a New Case and Literature Review

“…The clinical and radiographic data were available in the charts of the patient. The literature review included six articles of POT previously reported in the English-language literature [1,[8][9][10][11][12]. Thus, to the best of our knowledge, only 12 cases of POT have been reported to date, all of them affecting patients in the first two decades of life ( Table 1).…”

“…The term POT was first proposed by Mosqueda-Taylor et al [1], who reported a series of six cases of a previously undescribed odontogenic tumor with features similar to primitive dental papilla and follicle, arising in areas of missing or unerupted teeth of patients before adult life. Since then, six additional cases have been identified in the English-language literature [8][9][10][11][12]. We present an additional case in order to contribute to a better classification and understanding of this rare odontogenic tumor.…”

“…POT affected seven boys and five girls. Eight patients (66.6%) were in the second decade and four patients (33.3%) were in the first decade, with median age of 12.1 years (varying from 3 to 19 years) [1,[8][9][10][11][12]. The mandible was affected in ten cases (83.3%) [1,8,[10][11][12] and the maxilla in two cases (16.7%) [1,9].…”

The mandible was affected in ten cases (83.3%) [1,8,[10][11][12] and the maxilla in two cases (16.7%) [1,9]. Radiographically, POT presented as a unilocular or bilocular radiolucent appearance associated with an unerupted third molar in eight cases (66.6%) [1,8,12] or a first or second deciduous molar in four cases (33.3%) [1,9,10].…”

Primordial Odontogenic Tumour: A Systematic Review

“…Some issues about POT remain unclear and require future reports. The description of the odontogenic epithelium covering the ectomesenchyme was often contradictory, while it remains debatable whether peripheral ameloblastic islands or hard dental tissue deposition can occasionally occur within the tumor [3,4].…”
