This case report describes an ovarian endometrioma with markedly elevated CA-125 levels, ascites, and a large ovarian mass, initially misdiagnosed as ovarian malignancy.

This paper reports an unusual case of a very large ovarian endometrioma (about 20×20 cm) that presented with ascites and markedly elevated CA-125 levels, leading to an initial diagnosis of ovarian malignancy. The authors describe how CA-125, while often discussed as a tumor-associated biomarker, can also be increased in several benign conditions including endometriosis, though marked elevations are rarely reported in benign disease. A key caveat is that the findings are based on a single case report, limiting generalizability to broader populations or diagnostic accuracy. This paper is centrally about endometriosis — it specifically documents ovarian endometrioma causing a cancer-mimicking presentation with markedly elevated CA-125.

Abstract

Ca-125 is a cell surface glycoprotein present in epithelial ovarian tumors. It is called as a biomarker because it provides information about the biological state of a disease. It is also considered a “tumor associated protein” because elevated CA 125 levels do not always indicate ovarian cancer. Pelvic inflammatory disease irritable bowel disease, tuberculosis pancreatitis and endometriosis can also increase the Ca125 levels in these benign conditions the Ca 125 levels are rarely markedly. Here authors report a case of ovarian endometrioma with markedly elevated levels of Ca 125 who was diagnosed as a case of ovarian malignancy due to presence of ascites and a large ovarian mass of 20x20 cm size arising from the pelvis.
