Figure 3. Pathological examination of the hepatic mass revealed the outgrowth of atypical tumor cells with trabecular and partly tubular structures. The tumor cells were positive for synaptophysin and negative for chromogranin A. The Ki-67-positive cell ratio was 12%. The upper left shows HE, the upper right shows synaptophysin, the lower left shows chromogranin A, and the lower right shows Ki-67. Scale bars, 100 μm. HE – hematoxylin-eosin staining.
