Presentation of a Patient who Underwent Fertility-Sparing Surgeries for Contralateral Recurrence of Ovarian Immature Teratoma with Gliomatosis Peritonei

We report a patient who has maintained a regular menstrual cycle despite undergoing cystectomy and chemotherapy for contralateral recurrence of ovarian immature teratoma with gliomatosis peritonei. We initially performed a fertility-sparing right salpingo-oophorectomy, omentectomy and peritoneal biopsy for immature teratoma with gliomatosis peritonei, with adjuvant chemotherapy; we performed a left ovarian cystectomy and peritoneal biopsy for mature cystic teratoma with gliomatosis peritonei 16 months after the first surgery, a fertility-sparing left ovarian cystectomy and peritoneal biopsy for contralateral recurrence of ovarian immature teratoma with gliomatosis peritonei 60 months after the first surgery, and a left ovarian cystectomy and peritoneal and external iliac lymph node biopsy for endometrial cyst with gliomatosis peritonei 71 months after first surgery. The peritoneal gliomatosis lesions gradually decreased through the 4 surgeries over 8 years. The patient has maintained a regular menstrual cycle and currently shows no evidence of disease.
