A Rare case of Unusually Big Adenomatoid Odontogenic tumor.

Abstract

Of all odontogenic tumors, adenomatoid odontogenic tumors (AOT) are extremely rare, making for about 3% of cases. It is a benign, slowly developing, encapsulated, non-invasive, and non-aggressive odontogenic lesion connected to an impacted tooth. For years, these lesions could go undetected. The lesion does not return after the standard course of treatment of enucleation and curettage.

Here, we report an uncommon case of an unusually large AOT in a 16-year-old female patient from northeastern India, who presented with complaints of a swelling over her left side of face for past 5 years associated with bilateral nasal blockage. Clinical examination and investigations revealed a hard swelling with some cystic regions of size 7.6 (CC) x 7.2 (AP) x 6.6 (TR) cm. The patient underwent staged removal of the tumour and the histopathological examination of the cyst wall showed features suggestive of adenomatoid odontogenic tumor. The patient remains symptom free on a follow up period of 18 months.
