Figure 3

Pathological findings at autopsy. Macroscopic observation of the transverse cut surface of the right pulmonary artery showed the vascular lumen filled with the solid tumor and secondary thrombus (a). Gross appearance of the chest wall tumor that is occupying the full thickness from the soft tissue through the thoracic cavity (b). The cut surface of the chest wall tumor appeared as a white-colored solid mass with central necrosis (c). The left 6th rib bone showed the tumor with complete osteolysis. Microscopic observation in the pulmonary artery tumor showed that the tumor was predominantly composed of pleomorphic, multinucleated round tumor cells with an incohesive nature (d). TC, thoracic cavity; SCST, subcutaneous soft tissue; PL, pleura; 6R, 6th rib bone.
