Immature Teratoma in Pregnancy: A Case Report

Abstract

Immature teratoma is one of the rare malignant germ cell tumours presented in pregnancy. Here, we present 26-year-old pregnant women who had an incidental finding of left adnexal mass in an anomaly scan at 19 weeks of pregnancy. Laparotomy with peritoneal fluid cytology, left salpingo-oophorectomy and omental biopsy at 20 weeks of pregnancy revealed immature teratoma stage 1A, grade 2 in the histopathology report. However, she followed up with the metastatic mass in the pouch of Douglas at 30 weeks of pregnancy in magnetic resonance imaging despite being counselled for possible chemotherapy and surveillance. A baby with a good Apgar score and grade 3 immature teratoma in the metastatic mass was revealed following the exploratory laparotomy and cesarean section at 36 weeks of pregnancy. Fertility-sparing surgery with chemotherapy during pregnancy for high-grade tumours may result in a good prognosis.
