Pregnancy coexisting with serous papillary adenocarcinoma involving both uterus and ovary.

Less than 100 cases have been reported involving coexistent pregnancy and endometrial cancer of epithelial ovarian cancer. Only one case, histologically an endometrioid adenocarcinoma, demonstrated simultaneous involvement of endometrium and ovary. We report an additional case involving both uterus and ovary coexisting with pregnancy but of a serous papillary histology. A viable preterm infant was delivered. The mother is currently without evidence of disease on cisplatin-based chemotherapy.
