Extra-ordinary High CA-125 and CA19-9 Serum Levels in an Ovarian Endometrioma: Case Report

Endomet riosis is an estrogen dependent disease. levels of cancer antfgen-125 are significantly higher in women wit h moderate to severe endo metriosis. however, patients with unruptured endometriosis rarely have serum ca-125 levels more than 1000 u/ ml. this case report presents a diffuse,unruptured ovarian endometrioma in a 29- year-old woman, leading to an extraordinary high serum ca125 and ca19-9 levels; usually typical of advanced ovarian carcinoma. our experience emphasizes on benign gynecologic conditions such as endometrioma, which should be taken into account as a possible differential diagnosis in women with exaggerated elevation of the serum ca-125 level.
