Figure 2 (A). Expression of human chorionic gonadotropin by the neoplastic cells within choriocarcinoma areas is demonstrated by immunohistochemistry (arrows). (B). High-grade invasive urothelial carcinoma with choriocarcinoma areas. The latter (inset) is characterized by large polygonal cells with prominent nucleoli and occasional multinucleation, which represent cytotrophoblasts and syncytiotrophoblasts (arrows), in some areas directly lining blood vessel channels.
