A rare case of pelvic bronchogenic cyst treated by laparoscopic surgery.

A 31-year-old man with pain in his thigh was diagnosed with a benign presacral cystic mass. We performed laparoscopic subtotal resection of the cyst utilizing mobilization of a total mesorectal excision procedure used in low anterior resection for rectal cancer. Histopathological findings showed that the cystic lumen of the specimen was lined with pseudostratified columnar ciliated epithelium and had glandular structures and smooth muscle in its wall, leading to a diagnosis of bronchogenic cyst. The postoperative course was uneventful, and as of 6 months after surgery, the patient was doing well with no evidence of recurrence.
