An ovarian tumor larger than the patient's body weight

Surface epithelial-stromal tumors constitute by far the most important group among all ovarian neoplasms. Sixty-four kilogram left ovarian serous cystadenoma was removed from a forty-nine kilogram weighing Ethiopian woman. She presented with twenty-five years history of abdominal swelling. She had extreme degree of difficulty in bearing her weight, which resulted in keeping her to the house. This unusually big tumor is discussed with clinicopathologic correlation and literature review.
