Introduction:
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.
Conclusions:
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.
