Epidermal inclusion cyst mistaken for a post-traumatic chronic prepatellar bursitis a case report

ABSTRACT

A variety of cystic lesions are encountered around the knee joint. Particularly, the prepatellar region is the site of soft tissue lesions including mainly bursal fluid collections, joint synovial herniation and tendons ganglia. We report here the case of an exceptional prepatellar posttraumatic epidermal inclusion cyst mistaken for a prepatellar bursitis. With this case report, orthopedic surgeons should widen the array of the differential diagnosis in patients presenting with a post-traumatic prepatellar slow growing soft tissue mass, making epidermoid inclusion cyst a valid possibility to consider
