Gastroenteropancreatic Neuroendocrine Tumor with Hepatic Metastasis Misdiagnosed as Hepatocellular Carcinoma

The liver is the most common site of metastasis of neuroendocrine tumors (NETs). Gastroenteropancreatic (GEP)-NETs are rare, and the distinction between hepatocellular carcinoma (HCC) and metastatic NET can be difficult due to the similarity of their histological characteristics. Herein, we report a case of GEP-NET with hepatic metastasis, which was first misdiagnosed as HCC by liver biopsy and subsequently re-diagnosed after surgery as primary GEP-NET.
