    Abstract:
    INTRODUCTION: Extraperitoneal cysts in the pelvis adjacent to the rectum are rare entities. They are of vague etiology, and the pathologic types of the acquired variety are dermoid, epidermoid, and teratoma. As far as we know, laparoscopic excision of a retrorectal epidermoid cyst has never before been reported. CASE REPORT: The patient was an elderly lady with a large pelvic cyst and another large cyst in the perineum, which displaced the vagina and the anus. Laparoscopy was performed; the pelvic cyst was punctured and then dissected out. The perineal extension of the cyst was excised via a perineal approach. The patient had an uneventful recovery and was discharged on the 4th postoperative day. Histopathologically, the cyst was of the epidermoid type. Follow-up after 26 months revealed no recurrence. DISCUSSION: Our case presented a diagnostic dilemma. Laparoscopic excision was tedious, though we completed the procedure successfully. Precaution was taken to avoid spillage of the contents and also to avoid injury to vital structures nearby, such as the iliac vessels and ureter. It is feasible to laparoscopically excise retrorectal cysts with a careful and meticulous dissection. CONCLUSIONS: The major advantages are rapid recovery with minimal morbidity and excellent cosmesis.
