Laparoscopic excision of a mesenteric cyst diagnosed preoperatively as an ovarian cyst

Mesenteric cysts are uncommon benign, abdominal tumors usually managed by g eneral surgeons. We encountered an unusual mesenteric cyst that was diagnos ed preoperatively as an ovarian cyst. It was located in the pelvic cavity i nside the mesoappendix. We excised die cyst and adjacent vermiform appendix by laparoscopy. Histopathologic examination revealed mucinous cystadenoma. To the best of our knowledge, this is the first reported case of a mesente ric cyst removed by a gynecologic laparoscopist.
