Abstract

Ovarian cysts represent intra-abdominal neoplasms which attain a size large enough to fill the abdominal cavity. Cystic abdominal tumours are extremely common and nowadays are diagnosed more frequently due to availability of better imaging modalities. Presentations of huge cysts have become rare as most of them are diagnosed and treated early. Still we get reports of patients with huge benign abdominal cysts and majority of them are serous cystadenoma of ovary with less than 4% of all ovarian tumours being mixed epithelial type. Sometimes, it becomes very difficult to identify the source of these cysts and misdiagnosed as mesenteric cyst. Absolute diagnosis is only possible at laparotomy. We present a case of giant mixed seromucinous cystadenoma weighing 10Kg in a 65-year-old postmenopausal lady who underwent laparotomy with complete lack of intra-operative and post-operative complications attending the removal of a cyst of this size.
