Chest computed tomography (CT) scan showed an 4 cm pulmonary mass in the left lower lobe, without enlargement of intrapulmonary or mediastinal lymph nodes (Figure 1).
Histological results showed that the tumor was characteristic of choriocarcinoma, with large multinucleated cells representing syncytiotrophoblast admixed with medium-sized cells, often with clear cytoplasm, similar to cytotrophoblasts or intermediate trophoblasts (Hematoxilin Eosin 430X).
