Ovarian teratomas are a type of tumor that can develop in the ovaries, which are part of the female reproductive system. These tumors are made up of different types of tissues, such as hair, muscle, and even teeth, because they originate from germ cells. They can be classified as mature or immature, with mature teratomas being more common and usually benign. Most ovarian teratomas are asymptomatic, meaning they do not cause noticeable symptoms. However, some women may experience abdominal pain or discomfort. Diagnosis is typically made through imaging tests like ultrasound or CT scans, and treatment often involves surgical removal of the tumor.
