Single Unilocular Radiolucent Cyst in the Angle of Mandible of a Young Man: A Case Report

Abstract

The odontogenic keratocyst (OKC) is a noncancerous cyst that develops from the remaining cells of the odontogenic epithelium. The para-keratinised variant of OKC tends to be aggressive and recurrent. It has an array of features mimicking a variety of cysts that make the correlation of clinical, radiologic, and histopathological analysis necessary for definitive diagnosis and treatment planning. This is a case report of a 25-year-old male patient presenting with extra oral swelling in the right mandible and discharge from a peri coronal flap in relation to an impacted right lower third molar tooth. The radiograph indicated presence of a unilocular radiolucency, making it indistinguishable from other radiolucent cysts of the mandible. A diagnosis of OKC was made by analysing the aspirate acquired through FNAC. The cyst was enucleated, and Carnoy’s solution was applied. The histopathologic evaluation confirmed the diagnosis of OKC, and the patient is on regular follow-up with no signs of recurrence to date.
