Pelvic-peritoneal tuberculosis simulating ovarian carcinoma: report of three cases with elevation of the CA 125.

We report three cases of women with abdominal pathology in which an elevated serum CA 125 tumor marker could have led to an erroneous diagnosis of ovarian carcinoma. However, after peritoneal biopsies were taken, tuberculosis was diagnosed. Furthermore, specific tuberculostatic treatment normalized serum CA 125 levels.
