Fig. 3From: A rare case of intracardiac fibrosarcoma with myxoid features inducing venous occlusion in a dog – a case reporta Histolgic aspects of the mixed intracardiac tumor. Two microscopical aspects are visible: compact structure with spindle shape cells (star) consistent with fibrosarcoma and a myxomatous aspect, formed by pleiomorphic cells with cords, trabeculae and small groups distribution (diamond). Fibrosarcoma with myxomatous features - primary tumour; b Histological aspect of the fibrosarcomatous area of the mass: multiple mitotic figures are visible on 400× field (arrow); c Histological aspect of the myxomatous area of the mass: few mitotic figures are visible on 400× field (arrow).
