Fig. 6

Macroscopic and microscopic findings of the resected tumor. A Scale bar is cm. Cross-sectional appearances of the tumor after formalin fixation. Tumor necrosis induced by preoperative feeder embolization was noted as darkish area. Arrowheads point the flattened surface adjacent to the undersurface of the aortic arch. Arrows point the protruding surface of caudal end of the tumor adjacent to concaved pulmonary artery trunk. B Scale bar is 100 µm. Nests of cells with abundant cytoplasm were demonstrated (hematoxylin and eosin stain, × 200). C, D Scale bar is 100 µm. The tumor cells demonstrated positive staining for chromogranin A and synaptophysin (× 200)
