Malignant ovarian tumors associated with pregnancy: Report of six cases

Six cases of pregnancy associated malignant ovarian tumors, four epithelial cancers, one immature teratoma and one metastatic cancer of colon origin, are reported. One patient with mucinous cystadenocarcinoma had a history of persistent ovarian tumor during her past three pregnancies. Another patient was found to have mucinous cystadenocarcinoma after an emergency operation for twisted ovarian tumor. Immature teratoma associated with pregnancy is very rare and our case seems to be the 8th reported such case.
