Background: About 90% ovarian cancers are epithelial and 10-15% of this group are mucinous. The treatment is the hysterectomy with bilateral salpingo-oophorectomy.  However, most of these tumors occur in young women that have not yet given birth in which preservation of fertility should be considered. We present a case of huge mucinous cystadenoma and massive ascites managed by preserving uterus and ovaries. Meigs’ syndrome is found in fibroma, and thecoma of ovary, however, in rare occasion this syndrome is occurred in mucinous cystadenoma.
Case presentation: A 21-year-old unmarried woman presented with the complaint about weight gains and irregular menstruation for four months to gynecology clinic of Firoozgar hospital in Tehran in October 2016. Preop lab data including tumor marker was gathered, and sonography with CT scanning of pelvic and chest was performed. The ascitic fluid was negative for malignancy. Also, laparotomy with staging the ovarian tumors was carried out including cytology of ascitic-fluid, cytology of diaphragm, ovarian cystectomy, biopsy of the paracolic gutter, exploring abdomen and pelvis. Histopathology report revealed mucinous cystadenoma. Moreover, according to the normal appearance of the appendix in this case, the appendectomy was not performed.
Conclusion: Ovarian cysts in young women who are associated with elevated levels of tumor markers and ascites require careful evaluation. Management of ovarian cysts depends on patient's age, size of the cyst, and its histopathological nature. Conservative surgery such as ovarian cystectomy or salpingo-oophorectomy is adequate in mucinous tumors of ovary. Multiple frozen sections are very important to know the malignant variation of this tumor and helps accurate patient management. Surgical expertise is required to prevent complications in huge tumors has distorted the anatomy, so gynecologic oncologist plays a prominent role in management. In this case, beside of the huge tumor and massive ascites uterine and ovaries were preserved by gynecologist oncologist and patient is well up to now.
