Two Cases of Primary Hepatic Neuroendocrine Tumor

Abstract

Primary neuroendocrine tumor of liver is an extremely rare disease. We encountered two cases of hepatic neuroendocrine tumor. Case 1: A 65-year-old male was given a diagnosis of liver cyst adenoma. Partial hepatectomy was performed. Immunohistochemically, the final diagnosis was primary hepatic neuroendcrine tumor G2 (World Health Organization classification, 2010). Case2: A 72-year-old male patient was given hepatocellular carcinoma. Laparoscopic partial hepatectomy was performed. Immunohistochemically, the final diagnosis was primary hepatic neuroendcrine carcinoma G3 (World Health Organization classification, 2010). Here, we report two cases of rare primary hepatic neuroendocrine tumor together with a review of the literature.
