Giant mucinous cystadenoma: case report.

Mucinous tumours are the second most common type of epithelial ovarian tumours. Majority of these tumours are benign. However, some of these benign lesion can grow to enormous size, thus stimulating malignant neoplasia. This report presents the case of a 35 year old grand multiparous woman who came to our gynaecological clinic with 5 year history of abdominal swelling associated with weight loss. Abdomino-pelvic ultrasound scan revealed a large left ovarian cyst. She had laparotomy with left oophorectomy. A huge mucinous cystadenoma weighing 33.6 kg was removed. Her post-operative course was unremarkable.
