Intraplacental choriocarcinoma (IC) is a rare disease, occurring in approximately 1 in 50,000 pregnancies. A 33-year-old woman, gravida 2 para 0, sustained an intrauterine fetal death due to fetomaternal haemorrhage (FMH) at 36 weeks of gestation after presenting with decreased fetal movements in the days prior. The placenta macroscopically appeared normal. However, histological examination revealed an intraplacental choriocarcinoma. Assessment of this woman's quantitative beta human chorionic gonadotropin (bHCG) level was negative and a computerized tomography scan of her chest, abdomen and pelvis revealed no metastatic disease yet a bulky uterus. After discussion at a multidisciplinary tumour board meeting, the patient had endometrial curettings to rule out any uterine pathology and serial bHCG tests until one year post-partum. Following this, the patient successfully carried and delivered a live female term infant. Although FMH is a rare clinical manifestation of IC it should always alert clinicians to investigate the cause further, through urgent and careful histopathological examination of the placenta. This will allow for appropriate management with chemotherapy if indicated and a reduction in maternal morbidity and mortality.
