RESUMO
BACKGROUND: Gestational trophoblastic neoplasia rarely occurs in term pregnancies. Stage IV choriocarcinoma treated with conventional chemotherapy can result in death as a result of hemorrhagic sequelae at tumor sites. CASE: A 30-year-old woman at 34 weeks of gestation presented with a persistent cough, worsening dyspnea, and vaginal bleeding. Chest radiograph demonstrated innumerable lung nodules, and quantitative ß-hcg concentration exceeded 1.3 million milli-international units/mL. Cesarean delivery was performed for presumed abruption. Placental pathology demonstrated choriocarcinoma, and imaging confirmed stage IV disease with a World Health Organization score of 14. Remission was achieved after two courses of low-dose induction chemotherapy followed by 10 cycles of combination chemotherapy. CONCLUSION: Gestational trophoblastic neoplasia should be considered in a pregnant or postpartum woman presenting with atypical vaginal bleeding. Coexistent pulmonary or neurologic findings may suggest advanced disease.
