Glandular odontogenic cyst mimickers: A review and report of two cases

Abstract

Glandular odontogenic cyst (GOC) is a rare odontogenic cyst with a high recurrence rate. It is also associated with other odontogenic cysts and tumours. Odontogenic cysts with some histopathological features of GOC are termed as GOC mimickers (GOC-M). The diagnosis of a mimicker is challenging due to the lack of distinctive clinical and radiological features. Diagnosis is confirmed exclusively on histopathology. Specific guidelines based on histopathological features exist to recognize and delineate these mimickers from GOC. These features may be evident on incisional biopsy presenting an incorrect diagnosis of GOC leading to an erroneous overtreatment. On the contrary, overlooking these features in an incisional biopsy may result in misdiagnosis and under-treatment which increases the patient susceptibility to recurrence. This article reviews the enigmatic nature of GOC-M and presents two rare cases of the same in dentigerous cysts of the impacted supernumerary teeth in the anterior maxilla.
