Although both teratomas and ovarian cysts are in the adnexal region, teratomas present as cystic solid masses on ultrasound, whereas cysts present only as cystic masses, which is the fundamental difference between the two. Clinically, teratomas are subdivided into mature teratomas and immature teratomas, and the diagnosis is given mainly on the basis of pathology. In clinical practice, whether it is a teratoma or a pathological ovarian cyst, it is recommended to undergo surgery as soon as it is detected. It is also recommended to have a blood test for gynecologic tumors before the surgery in order to know if there is a possibility of malignant lesions. It is best not to have intercourse for 3 to 7 days after your menstrual period and go to the hospital first to check the white belt routine. If there is no bacterial infection, you can be admitted to the hospital to give surgical treatment.
