A Rare Case of Recurrent Mucinous Cystadenoma in Pregnancy

Ovarian mucinous cystadenomas are second most common type of benign epithelial ovarian tumors. They may be intra peritoneal or retroperitoneal, of which intraperitoneal tumors are commonly seen while primary retroperitoneal mucinous cystadenomas (PRMCs) are very rare. Our is a case of a 26-year-old pregnant woman in whom recurrent ovarian cystadenoma was operated successfully. Mucinous cystadenoma recurrence is apparently not as rare as reported in the literature. The unique feature in our case, was that patient had fourth time recurrence of mucinous cystadenoma, despite undergoing, twice laparoscopic and once laparotomy removal of cyst on previous three occasions. The recurrence may have been due to intraoperative cyst rupture or conduct of cystectomy during previous surgeries. Also in our case, the recurrent tumor was retroperitoneal in nature which may have been because of two possibilities first, the tumor may have been intraperitoneal at first onset and became retroperitoneal during recurrence due to cyst rupture and spillage of mucinous material in the cavity during previous surgeries, second, the tumor may have been primarily retroperitoneal, although a rare phenomenon. The incidence for primary retroperitoneal cystadenoma is around 10 for every one million hospital admissions.
