Adolescent and Pediatric Ovarian Tumors

The incidence of ovarian tumors in adolescents and children at this age is relatively rare. The incidence of ovarian tumors under the age of 20 is only 5% to 10%, but during this age, ovarian tumors are the most common. The most common ovarian tumors in adolescents and children are germ cell tumors, including teratomas, asexual cell tumors, endodermal sinus tumors, embryonal cancer, and primary choriocarcinoma, accounting for about 60%, and adults account for only 20%. There are significant differences in ovarian tumors in young, adolescent and adult. 70% to 80% of ovarian tumors in adults are epithelial tumors, while epithelial tumors in patients under 20 years old account for only 17%, and borderline tumors are rare. Some scholars have reported the incidence of epithelial tumors, 0.5% for 9-year-olds, 16% for 10-13 years old, and 38% for 14-17 years old. For children, adolescents should carry out a census physical examination, if necessary, pelvic and B-ultrasound, CT examination. Try to preserve fertility in the treatment.
