Duplication is a rare congenital abnormality and may occur in any region of the gastrointestinal tract. A 19-year-old woman was admitted due to lower abdominal pain. Abdomino-pelvic CT scan showed a cystic mass interpreted as mesenteric cyst or duplication cyst. On the operation finding, it seemed to be arised from mesentery but attached to the ileum. Microscopically, the cystic wall was lined by non-keratinizing squamous, ciliated pseudostratified columnar epithelium, and ectopic gastric mucosa with two distinct muscular layers and a serosa. We report the first case of ileal duplication cyst lined by squamous and ciliated columnar epithelium in Korea.

PURPOSE: A seminal vesicle cyst in combination with ipsilateral renal agenesis is rarely encountered. We present cases of this disease entity with symptoms, which were treated with a laparoscopic approach as a minimally invasive surgical treatment. MATERIALS AND METHODS: We experienced 4 patients with seminal vesicle cysts and ipsilateral renal agenesis. The mean age was 45.8 years. Chief complaints were perineal pain and hematospermia. Seminal vesicle cysts and remnant ureters were excised by laparoscopic surgery with transperitoneal approaches. RESULTS: The mean operative time was 133.8 minutes. The mean hospital stay was 6.8 days. There were no operative complications or transfusions. CONCLUSION: In our report, patients of congenital seminal vesicle cyst associated with renal agenesis are presented. Laparoscopy is considered a minimal invasive management of these combined anomalies, providing a good image and an easy approach.
