Macroscopic features of the suspected ULMS metastasis to the epicardium, surgical technique and histopathology of the tumour. a) Intraoperative finding - the tumour (interrupted line) is on the apex of the heart and completely free from the parietal layer of the pericardium (arrows); b) tumour mass after resection; c) defect of the left ventricle after resection of the tumour with polypropylene sutures placed around the defect; d) defect of the ventricle reconstructed with a polyester patch; e) histopathology - tumour cells (asterisk) infiltrate myocardium but not endocardium (HE staining, x2); f) histopathology - tumour cells are spindle-shape, pleomorphic with high mitotic activity (HE staining, x40)
