title: A case of primary retroperitoneal mucinous cystadenocarcinoma.
abstract: A rare case of primary retroperitoneal mucinous cystadenocarcinoma in a 44-year-old woman is reported. The cystic tumor was delineated by CT and echography. The tumor was removed intact in the presence of bilateral normal ovaries and demonstrated an infiltrating malignant process. This neoplasm may have arisen from a supernumerary ovary. The patient died of recurrence 4 months after surgery. A comparison of the known cases indicates that aggressive treatment by hysterectomy with bilateral salpingo-oophorectomy in addition to cyst extirpation may improve prognosis.
