Hemoptysis as primary manifestation in three women with choriocarcinoma with pulmonary metastasis: a case series

摘要

BackgroundGestational choriocarcinoma is the most common gestational trophoblastic neoplasia; it is often secondary to hydatidiform mole, as well as to abortion, ectopic pregnancy, premature delivery, or term delivery. Approximately 60% of patients with choriocarcinoma develop pulmonary metastases, but for patients with a respiratory condition, choriocarcinoma with lung metastasis is a relatively rare lung cancer diagnosis. Three cases of choriocarcinoma with pulmonary metastasis who had the primary symptom of hemoptysis are described.
