Pelvic Retroperitoneal Epidermoid Cyst: A Rare Case

Epidermoid retrorectal cystic tumors are rare and uncommon lesions that are generally asymptomatic, the appearance of symptoms such as pain or neurological disorders should raise suspicion of degeneration. We report the case of a 35 year old woman who was found to have a renitent, painless lump compressing the posterior wall of the rectum while having a history of painful discomfort while sitting. The diagnosis was confirmed after discovering a well- circumscribed presacral mass on computed tomography (CT) scan and MRI. She underwent a posterioc laparoscopy and the excision of the encapsulated cystic mass was later confirmed to being an epidermoid cystic tumor. Finally, due to the risk of infection and malignant transformation, these tumors must be managed with a multidisciplinary approach to maximize successful treatment.
