Figure 1 Histology of the cardiac mass showing a uniform proliferation of spindle cells on a collagenous myxoid background, with medium cellularity, mild to moderate pleomorphism and prominent vascularization. Haematoxylin-eosin, original magnification: A: 100 ×; B: 200 ×; C: 400 ×; Diffuse immunostaining for vimentin, D: 200 ×; and multifocal immunostaining for smooth muscle actin, E: 200 ×; Ki-67 labeling index: ca 35% of tumor cells, F: 200 ×.
