title: [Epidermal cyst of the parotid gland].
abstract: Epidermoid cysts of the parotid gland are rare. We report the case of a 60-year-old man with a cystic tumor of the right parotid gland. The patient had undergone ipsilateral middle ear surgery twice four years previously. The tumor was identified by computed tomography and ultrasonography and removed by total parotidectomy under suspicion of a parotid tumor. Histopathology revealed the diagnosis of an epidermal cyst. The differential diagnosis of a parotid tumor should include (iatrogenic) epidermoid cyst, in particular if there is a history of prior ear surgery via an endaural approach.
