Teratomas are divided into mature and immature teratomas. Mature teratomas, also known as dermoid cysts, are benign tumors, commonly found in individuals aged 20-40, usually unilaterally. The contents of the cyst typically include substances like sebum, hair, and teeth. Immature teratomas, on the other hand, are malignant tumors, though less common. They have a higher rate of recurrence and metastasis. Surgical treatment is generally recommended for teratomas, while medical treatment is not advised. Less frequently, laparoscopic surgery can be used for certain teratomas. If a teratoma is suspected to be malignant preoperatively, exploratory laparotomy is often performed. Postoperative outcomes are generally better for benign mature teratomas. In cases of malignant teratomas, chemotherapy may be required after surgery.
