Giant Cystic Mucinous Borderline Tumour of the Ovary in a Young Female: A Rare Case Report.

Giant mucinous borderline tumours of the ovary are an unusual finding and pose a diagnostic challenge. We present a case of a 20-year-old unmarried, nulliparous female who presented with left quadrant pain and a progressively increasing abdomino-pelvic mass. Based on clinical and radiological investigations, a provisional diagnosis of mass arising from the ovary was made. The histopathological evaluation revealed it to be a mucinous borderline ovarian tumour.
