title: Combined epithelioid trophoblastic tumor and contralateral synchronous adenocarcinoma of the lungs in a 69-year-old man.
abstract: An epithelioid trophoblastic tumor (ETT) is a form of gestational trophoblastic neoplasms that arise from trophoblasts. The tumor generally occurs in women of reproductive age and has a characteristic growth pattern and immunohistochemical profile. We present an extremely rare case of a primary ETT occurring in the lungs with an adenocarcinoma in the contralateral lung as synchronous double primary lung cancers in a 69-year-old man who had no history of a remote malignancy. He underwent adjuvant radiotherapy to both lungs after a staged thoracoscopic wedge resection and was doing well without recurrence or metastasis up to last follow-up.
