Microscopic appearance of the specimen (hematoxylin and eosin staining). A: Tumor-adjacent liver parenchyma showed portal cirrhosis (magnificaton × 100); B: A transitional zone could be defined between the carcinomatous (lower left) and sarcomatous components (upper right). There were intermingled cells of the two elements (magnificaton × 100); C: Foci of cholangiocellular carcinoma with various grades of differentiation (magnificaton × 100); D: Neoplastic osteoid and chondroid formation was observed in the sarcoma element (magnificaton × 100); E: Metastasis nodule was composed of undifferentiated sarcoma cells with deeply stained nuclei (magnificaton × 40); F: Higher-magnification view of the squared part in panel E.
