ABSTRACT
This article reports the case of a 40 year old woman who presented to the gynaecologic outpatient clinic with pain lower abdomen and an abdominopelvic lump. Clinical assessment, biochemical and radiological investigations revealed bilateral complex ovarian masses. Surgical exploration and histology of ovarian masses confirmed a rare bilateral borderline seromucinous cystadenoma.

This article also provides overview of the pathology and biology of borderline ovarian tumours, diagnosis, principles of surgical management and to appreciate the value of follow up.
