Fig. 3

Metastatic placental site trophoblastic tumor (PSTT) in the lung. Section showed multiple metastatic tumor nodules (A) in the lung which displayed similar morphology to that of the ovarian lesion (B). The tumor cells were diffusely immunoreactive for hPL (C) and Gata3 (D), and had only rare hCG-positive cells (E). HSD3B1/Ki67 double stain showed increased Ki-67 proliferation index in HSD3B1-positive cells (F)
