Abstract

Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is an extremely rare tumor. Only 30 cases have been reported previously in the English literature, and little information is available concerning its treatment and prognosis. The patient was a 28-year-old woman, presenting with a right mid-abdominal tumor at 26 weeks of gestation. At 31 weeks of gestation, she underwent an exploratory laparotomy and was diagnosed with a PRMC. No disseminated tumor was observed, and an excision of only the tumor was performed. She had an uneventful vaginal delivery at 38 weeks of gestation and remains free of disease at 13 months after the operation. This report describes a case of PRMC associated with pregnancy. The optimal management of these retroperitoneal masses during pregnancy is discussed. Based on limited experience and the current literature, a PRMC with an intact capsule and no dissemination appears to have a good prognosis and can be treated by tumor excision alone in patients who wish to preserve fertility
