Successful pregnancy outcome with coexisting primary epithelial ovarian carcinoma.

: Maternal epithelial ovarian cancer (EOC) is rare. EOC is reported to occur in 1:12,000 to 1:50,000 pregnancies. We report a case of Stage IA epithelial ovarian cancer detected in the first trimester managed by laparotomy at 13 weeks followed by left sided salpingo-oophorectomy and infra-colic omentectomy. Histopathology revealed papillary mucinous cystadenocarcinoma (well differentiated with negative peritoneal cytology for malignancy). Chemotherapy was not warranted due to early stage disease and she had an uneventful gestation ending in vaginal delivery of a 2.5 kilogram male baby at term. During the period of follow up she developed no clinical or biochemical evidence of tumour recurrence or relapse.
