title: Single synchronous pulmonary metastasis from placental site trophoblastic tumor and teratoma.
abstract: Placental site trophoblastic tumor (PSTT) is a rare variant of gestational trophoblastic tumor (GTN), accounting for 1-2% of all GTNs. Primary testicular PSTTs are extremely rare. Thirty percent of patients with PSTT show multiple lung and brain metastases at the time of diagnosis. We present the first case of a synchronous single pulmonary trophoblastic placental tumor metastasis together with a teratoma and a mixed germinal tumor of the testis, treated with minimally invasive lung metastasectomy.
