Metastatic epithelioid trophoblastic tumor of the lung: A case report.

Rationale: Epithelioid trophoblastic tumor (ETT) is a very rare form of gestational trophoblastic disease (GTD) which arises from neoplastic proliferation of intermediate trophoblasts. Metastatic ETT of the lung is extremely rare in postmenopausal women.

Patient Concerns: Here we describe a 50-year-old woman with a metastatic ETT of the lung showing increasing tracer uptake at PET/CT.
