case_images: The whole testicular boundary was unclear, the epididymis was enlarged, and the tunica albuginea had a visible tear of approximately 1.5 cm in length (Figure 4).
case_images: He x 20: The tumor cells were arranged in fascicles, and some were nestled in some areas. The nucleus was fusiform and oval, and the cytoplasm was rich and acidophilic.
