title: Extrauterine Epithelioid Trophoblastic Tumor of Lung in a 35-year-old Woman.
abstract: Extrauterine epithelioid trophoblastic tumors constitute an extremely rare gestational trophoblastic disease. We report the case of an extrauterine trophoblastic tumor that was incidentally detected in the left lung. Squamous cell carcinoma was suspected after microscopically examining the specimen obtained upon preoperative needle biopsy. After surgery, the tumor was confirmed by microscopic findings and immunohistochemical features.
