Comparative Clinical Analysis of Gastroenteropancreatic Neuroendocrine Carcinomas with Liver Metastasis and Primary Hepatic Neuroendocrine Carcinomas

Figure 3

Immunohistochemistry of hepatic neuroendocrine carcinomas. (a) Histological examination showed crowded cells in the liver, striking karyokinesis, and a significantly increased karyoplasmic ratio (×100). (b) Histological examination showed atypical carcinoma cells, partially low regional differentiation, and significantly increased mitoses close to the surrounding liver invasion (×100) caused by the karyoplasmic ratio. (c) Immunohistochemistry revealed that the tumor cells were positive for Syn (×100). (d) Immunohistochemistry revealed that the tumor cells were positive for CgA (×100).
