An epithelial trophoblastic tumor (ETT) is a kind of rare trophoblastic tumor that may have the correlation with a prior gestational event. Especially, the one that appears in the lung is extremely rare.

Case summary:

Here, we present a 24-year-old female patient with the chief complain of vaginal bleeding for more than 1 month, who was found to have a large mass (7.5 × 4.5 cm) in the right lower lobe, and it was finally confirmed as lung ETT by postoperative pathology after a successful radical resection of the pulmonary lobe.


As the reason of an extreme rare occurrence of the ETT, doctors can easily misdiagnose the disease. When the patient was found to have a mass with irregular vaginal bleeding and a high level of beta-human chorionic gonadotropin, we need to consider ETT. Currently, surgery is still the most effective method.
