Gestational trophoblastic disease occurs in 1–3:1000 gestations worldwide. Up to one-fifth of complete hydatidiform moles undergo malignant transformation, with 2%–4% manifesting as metastatic disease. Of these, a third present with vaginal metastases, which can cause bleeding and discharge. We describe the case of a 49-year-old primiparous woman presenting with syncope and intense bleeding from an anterior vaginal lesion, 3 weeks after uterine evacuation for a presumed spontaneous abortion. A vaginal metastatic nodule was suspected; haemostasis was achieved with vaginal packing, precluding the need for surgical intervention. The patient was ultimately diagnosed with invasive mole with vaginal and lung metastases (stage III high-risk gestational trophoblastic neoplasia (GTN)) and started on multiple-agent chemotherapy. Two months later the lesion had regressed completely, and remission was reached 2 weeks later. Clinicians should consider the possibility of metastatic GTN with vaginal involvement whenever heavy vaginal bleeding follows a recent history of failed pregnancy.

Contributors CC identified the case and, together with MB, initially managed the patient. DD was involved in the staging and gynaecological follow-up of the patient, while Dr Adélia Félix, an Oncologist at our institution, defined the treatment plan and oversaw its implementation and follow-up. RM and CC had the idea to publish the case. RM performed the literature research and wrote the article; CC was a major contributor in revising the manuscript. All authors read and approved the final manuscript.
