Extremely elevated serum CA125 and CA19-9 levels following the rupture of ovarian endometrioma: a case report

In gynecology, the serum CA125 and CA19-9 levels are elevated in patients with malignant and benign conditions especially in ovarian tumors. Although endometriosis is a benign condition, increased levels of the tumor markers CA125 and CA19-9 may be seen. We present a case demonstrated that abnormally high levels of plasma CA125 and CA19-9 encountered in bilaterally large ovarian endometrioma with rupture and the overflow of the thick chocolate cyst fluid throughout the abdominal cavity.
