Pelvic epidermoid cyst: A rare cause of lower urinary tract symptoms.

Pelvic retroperitoneum is a bizarre location of an epidermoid cyst and obstructive voiding caused by it even being stranger. Voiding symptoms related to such an abnormal location of cyst are extremely rare and literature that taps into such cases is scarce. We are presenting here a case of 26-year-old man who was presented with obstructive lower urinary tract symptoms and chronic constipation. On evaluation, he was found to have well-defined cyst in pelvic retroperitoneum. Complete excision of the cyst was done; histopathology confirmed it as an epidermoid cyst. His symptoms were completely relieved over a 12-month follow-up. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018. All rights reserved.
