A rare case of an intraosseous epidermoid cyst of the posterior maxilla

Abstract

An epidermoid cyst (EC) is a benign soft tissue lesion that can form in any part of the body. However, the occurrence of EC in the maxilla is extremely rare. Herein, we report a rare case of an intraosseous EC located in the posterior region of the maxilla. A 13-year-old woman was referred to our department for evaluation of an intraosseous radiolucent lesion in the right maxilla. The asymptomatic lesion appeared well-defined and unilocular (15 × 20 mm) on the panoramic radiograph and computed tomography scan, and was surgically extracted under general anesthesia. Based on the results of the histopathological examination, a final diagnosis of EC was confirmed. EC should be included in the differential diagnosis of radiolucent lesions of the jaws and maxilla.
