A Case of Pararectal Epidermoid Cyst Removed by Sacral Approach

: A 30-year-old woman was admittedto the hospital because of fecal occult bloodpositivity . Endoscopic colonoscopy indicated pressure on the right side of the rectum from the wall. Abdominal contrast CT and pelvic MRI revealed a cystic lesion with a maximum diameter of 5 cm on the pre-coccyx andthe right side of rectum. There was no continuity between the tumor andthe uterus/ovary. We diagnoseda pararectal tumor andremovedit via a sacral approach. The cyst was diagnosed as an epidermoid cyst. She was discharged on the 5th postoperative day. We could resect the tumor completely, because we chose an appropriate approach, considering the position, developmental direction, and size of the tumor.
