Ovarian cystic solid mass is benign or malignant preoperative can not be determined, preoperative ovarian tumor marker examination, pelvic magnetic resonance and other approximate judgment and to determine the mode of surgery, the main judgment of benign and malignant need to be operated to cut off the ovarian cyst sent to the pathology examination in order to confirm the diagnosis. 1. benign: most benign tumors are cystic, but there are also a small number of benign tumors are cystic solid, benign tumors are generally unilateral, activity is relatively large, the surface is smooth, and there is no adhesion with the uterus, generally there is no peritoneal fluid, the more common is mature teratoma and so on. 2. Malignant tumors: If the ovarian cystic solid mass is bilateral, the surface is uneven and nodular, and accompanied by abdominal fluid, ultrasonography found liquid dark, there is a messy light in the area, the mass of light spots, the mass border is not clear, consider malignant, may be epithelial tumors, germ cell tumors, gonadal cord – mesenchymal tumors, and so on. Ovarian cystic solid mass alone can not accurately determine the nature of the tumor, it is recommended that the discovery of ovarian cystic solid mass, timely consultation, standardized treatment under the guidance of physicians. The final judgment of ovarian cystic solid mass also needs to peel off the mass during surgery and send it to the pathology examination, so that the nature of the mass can be diagnosed conclusively.
