Clinical, Radiological features of Calcifying Epithelial Odontogenic Tumor: Report of two rare cases

Abstract

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic tumor constitutes around 1% of all odontogenic tumours involving the jaw. The intraosseous and extraosseous variant constitutes about 95% and 5% of CEOT respectively. We have reported two CEOT cases. One is associated with an impacted left third molar in the maxilla of 39-year-old female patient, and the other with a sessile soft tissue gingival mass in the left molar region of a 30-year-old female patient. It also emphasizes the importance of advanced imaging and peculiar findings of computed tomography in diagnosing this rare tumour. The visualization of the internal structure of the lesion and the involvement of the neighbouring structures were considered very helpful for diagnosis and treatment planning. Early detection and treatment planning for such rare cases is required to prevent further complications.

Calcifying Epithelial Odontogenic Tumour (Pindborg Tumour): Report of Two Clinical Cases with A Rare Maxillary Localization

“…In the mandible, the tumor is frequently associated with the impacted mandibular molars, in which mandibular second molar is more common as compared to the first and third molars. In the present cases, the lesion was in the maxilla unilocular for the first case and bilobed for the second case, both with well-defined borders [5,[8][9][10][11].…”

“…The central type of CEOT is usually asymptomatic for longer periods and a bony hard swelling is evident only in the advanced stages of the tumor. Other signs can be accompanied, in particular the mobility and dental displacement [5]. In the first case of central CEOT patient has swelling for the last 2 years with mobility and dental displacements.…”

“…To prevent the recurrence of the treated cases of CEOT periodic follow up is necessary. Five years minimum follow up period is necessary for treated patients [5].…”

“…Patients with CEOT are therefore followed up every 3 months. Patients are also monitored and regularly evaluated for recurrence [5].…”

“…Most patients of central and peripheral type CEOT are above 40 and 35 years of ag[5]. The first reported case, the patient was 28 years old, while in the second case, the patient was 18 years old.Approximately 90% of CEOT cases are intraosseous, and the mandible is the most affected site in these patients.…”
