Abstract:

Malignant ovarian germ cell tumor(MOGCT) are derived from primitive germ cells of embryos and occur mostly in children, adolescents and young women, so preserving the function of reproduction must be taken into consideration. We report a case of a 15-year-old girl presented with acute left lower abdominal pain after exercise. Transabdominal color ultrasound suggested a hypoechoic mass in the pelvic cavity and a ruptured left ovarian mass which caused massive intraperitoneal hemorrhage was found via laparoscope. Unilateral salpingo-oophorectomy was admitted, and serum alpha fetoprotein(AFP), carbohydrate antigen 19-9(CA19-9) and human chorionic gonadotropin(hCG) were increased postoperatively. Pathological results revealed a mixed ovarian germ cell tumor with dominant components of embryonal carcinoma and choriocarcinoma, and a few yolk sac tumor and teratoma. On the 11th day after surgery, positron emission tomography(PET)/CT showed no residuals. Four cycles of chemotherapy with the regimen of Ping-Yangmycin+etoposide+cisplatin (BEP) were performed. Her serum AFP and hCG came normal after two cycles of chemotherapy. Menstruation was resumed by February 2022 and there was no signs of recurrence until May 2022.
