Background: Ovarian dysgerminoma, a subtype of malignant germ cell tumor (GCT), is a rare ovarian neoplasm that is infrequently found in the gravid patient. When dysgerminomas do occur in pregnancy, the rapidly growing tumors can have a heterogeneous presentation and lead to peripartum complications and morbidity. Due to the rarity of this condition, diagnostic and therapeutic strategies are not well described in the literature. Case presentation: A healthy multigravida with an uncomplicated antenatal history presented for elective induction of labor. She had a protracted labor course, persistently abnormal cervical examinations, and eventually developed a worsening Category II tracing that prompted cesarean birth. Intraoperatively, a 26 cm pelvic mass later identified as a Stage IA dysgerminoma was discovered along with a massive hemoperitoneum. The mass was successfully resected, and the patient remains without recurrence 6 months postoperatively. Conclusion: Although rare and generally indolent, dysgerminomas can grow rapidly and cause mechanical obstruction of labor and other complications in pregnancy. Pelvic masses, including malignant neoplasms, should be included in as part of a broad differential diagnosis when evaluating even routine intrapartum complications such as abnormal labor progression. Additionally, we demonstrate that adnexal masses can be a source of life-threatening intraabdominal hemorrhage.
