Core Tip

Core tip: Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare and difficult to diagnose before preoperative biopsy or surgery. This case report shows that the diagnosis of PHNET is a medical challenge. Thus differentiation of PHNET from other hepatic mass and exclusion of occult primary neuroendocrine tumors are necessary. The diagnosis of PHNET can be ascertained after long term follow-up to exclude another primary origin.
