title: Posttraumatic gluteal epidermal cyst with ischiorectal and presacral extension.
abstract: An unusual case of rapid-growing posttraumatic gluteal epidermal cyst with ischiorectal and presacral extension is reported. Pertinent clinical history and magnetic resonance imaging allowed accurate preoperative diagnosis. Cautious complete excision was important to prevent recurrence. To our knowledge, posttraumatic gluteal epidermal cyst with this unusual clinical presentation has not been described previously.
