Laparoscopic Ablation of a Pelvic Retroperitoneal Epidermoid Cyst

Experience with minimally invasive approaches, such as laparoscopic ablation and transanal endoscopic microsurgery, to resection pelvic retroperitoneal and presacral tumors is limited. Masses arising from this anatomic position are usually removed using a transsacral approach or laparotomy. We report a detailed description of the laparoscopic procedure performed in a 32-year-old woman to remove a mass, which was detected with both ultrasonography and magnetic resonance imaging, that was closely adherent to the left sacrospinous ligament and compressing the rectum. Histopathologic findings were consistent with a rare case of pelvic retroperitoneal epidermoid cyst. This tumor, which usually occurs in the face, the scalp, the trunk, or the neck, has been described in the pelvic retroperitoneal space in only a few cases.
