Florid Adnexal Polypoid Endometriosis Associated with Very High Serum CA-125 Levels Mimicking Ovarian Malignancy

We report a case of florid polypoid endometriosis presenting with advanced bulky disease in pelvis with serum ca-125 levels of 7844u/ml. the extent of tumor, ct scan findings, elevated serum ca-125 levels were suggestive of ovarian malignancy. histopathology demonstrated endometrial glands and stroma. glands were neither crowded nor complex and were separated by a fibromatous stroma that contained endometrial stromal cells. these features were consistent with diagnosis of polypoid endometriosis, a recently described entity with a clinical presentation completely different from conventional endometriosis. our case emphasizes the association of high levels of ca-125 with benign gynaecologic conditions.
