Pathology reports an ovarian serous cystadenoma weighting 30 kg and uterine fibroids, Postoperative course was uneventful. In spite of accessible diagnostic imaging as ultrasound, we still find cases as the one we had described. There has not been reported a mass of this weight in our Institution before.
