title: Pulmonary mass diagnosed as extrauterine epithelioid trophoblastic tumor.
abstract: Pulmonary extrauterine epithelioid trophoblastic tumors (ETTs) are extremely rare. A 26-year-old nonsmoking woman with a history of a suspected subclinical miscarriage presented with a large mass in the right lower lobe that was confirmed to be a pulmonary extrauterine ETT using immunohistochemical stains. When a nonsmoking fertile woman presents with a pulmonary mass and an elevated serum β-human chorionic gonadotrophin in the absence of gynecologic disease, pulmonary extrauterine ETT should be considered.
