Histologically, the tumor exhibited a permeative growth pattern and was composed of uniformly high-grade round cells with brisk mitotic activity arranged in tight nests separated by a delicate capillary network (Figure 3).
Microscopic examination reveals the presence of an extensive lymphovascular space invasion in the myometrium (H&E staining; 4x).
