A Large Mature Teratoma in a Postmenopausal Women.

Mature cystic teratomas arise from three germ lines: ectoderm, mesoderm, and endoderm. They have a certain malignant potential, which is a diagnostic and therapeutic challenge. They occur very often in young women, but there are a significant number of postmenopausal cases where the risk of malignancy is greater. Symptoms may be nonspecific, but in the event of complications, an acute condition may develop, threatening the patient's life. Treatment depends on the risk of malignancy, age, and presence of complications. We present a case of a postmenopausal woman with a large mature teratoma of the left ovary involving elements from all three germ lines. A laparotomy and hysterectomy with bilateral salpingo-oophorectomy were performed, considering the patient's age and risk of malignancy. Given the risk of complications and malignancy in patients with mature teratoma, early detection, correct diagnosis, and therapeutic management are crucial for a higher chance of a successful outcome.
