Primary Hepatic Neuroendocrine Tumor: A Case Report and Literature Review

Primary hepatic neuroendocrine tumors (PHNETs) are an utterly rare subtype of neuroendocrine tumors (NETs) that arise from cells of the neuroendocrine system. Due to the rarity and lack of distinctive radiological features, diagnosis and management of this tumor are challenging. Herein, we report a case of PHNET in a 19-year-old previously healthy female patient whose diagnosis was confirmed by histopathology and immunohistochemistry. This case emphasizes the importance of considering PHNETs in the differential diagnosis of a hepatic mass, management of patients with this disease, and post-operative follow-up.
