An epidermal cyst in the parotid gland following ear surgery: a case report. Problem/objective: Iatrogenic epidermal cysts have been reported in various locations following otological surgical procedures. Especially after endaural incisions, surgeons may implant squamous epithelium into underlying tissue. An epidermal cyst of the parotid region may appear years after ipsilateral ear surgery.
Methodology: A cystic lesion in the superficial lobe of the parotid gland was identified by computed tomography and ultrasonography in a 30-year-old man with a history of myringoplasty and endaural surgery. A superficial parotidectomy was performed to remove the mass.
Results: The mass was histopathologically diagnosed as an epidermal cyst.
Conclusion: If a cystic lesion is present in the parotid gland in a patient with a history of otologic surgery, it must be considered that the mass is of epidermal origin.
