Microscopic view (hematoxylin-eosin staining; magnifications: A and B: x 100, C: x 40, and D: x 10) of the large cardiac tumoral mass (sarcoma). Sections show that the mass is composed of spindle to oval neoplastic cells with a high nuclear-cytoplasmic (N/C) ratio and mitosis. Additionally, there are some foci with a fascicular pattern, necrosis, and hemorrhage.
